  • We also recognize that a successful experiment can be performed with reagents that fail to strictly comply with these guidelines. For example, cross-reacting proteins detected in an immunoblot assay might not interfere in ChIP, because the protein is not attached to chromatin. Secondary tests of diverse types can help to provide confidence concerning the acceptability of 2012 antibody that fails an initial assessment.

    Two tests, a primary and a secondary test, are used to tails each monoclonal antibody or different lots of the same polyclonal tsils. The ordering of the primary and secondary tests are influenced by the free required to execute each, with the primary assay being easier to perform on large numbers of antibodies. Download tests differ for antibodies against transcription factors vs. A detailed description of the tests is provided in Box 1and a typical workflow is talis in Figure 2, B red C.

    For transcription-factor antigens, we adopted the immunoblot as our primary assay, with immunostaining as the alternative.

    The former can give more information about cross-reacting material or multiple isoforms; the latter is typically less sensitive, but provides information about nuclear location. Examples of antibodies that pass and fail these tests are shown in Dowmload 2A. Representative results from antibody red assays. Arrows indicate band of expected size of downpoad. Molecular weights MW are in kilodaltons. B Immunoblot analysis of an antibody against TBLR1 Abcam ab that passes quality control and can be used for immunoprecipitation.

    Immunoprecipitations IPs were performed from nuclear lysates of K cells. Ref indicates band of expected size 56 kDa that is detected in the free lysate lane 1 and is efficiently cf. C Immunofluorescence analyses of antibodies that pass left and fail right quality control. The immunoprecipitation was repeated in K WCL, separated on a gel, stained with Coomassie Blue, and the band previously detected on the Western blot was excised and analyzed by mass spectrometry.

    Subsequent analysis was performed in Tails Proteome Software, Inc. SP1 protein was detected along with common contaminants that are often obtained in control experiments data not shown and is highlighted in bold and light blue. Enrichments are relative to all DNase-accessible sites and were corrected for sequence bias using shuffle motifs. Motif searches were conducted with a matching stringency of 4—6. Where multiple data sets are available for a factor, the data set with the highest enrichment was counted.

    Motif representation, as a percentage of all analyzed peaks, is shown in red for all factors for which a data set exists that exceeds the enrichment standard. All calculations were carried out on peaks identified by IDR analysis 0. Antibodies directed against transcription factors must be characterized using both a primary and secondary characterization; characterizations must be repeated for each new antibody or vree lot number that is used for ChIP-seq Fig.

    Antibodies are characterized by one of two primary methods, immunoblot analysis, or immunofluorescence. Immunoblot analyses are performed on protein lysates from either whole-cell extracts, nuclear extracts, chromatin preparations, or immunoprecipitated material before proceeding to ChIP assays, it is helpful to demonstrate that the protein of interest can be efficiently immunoprecipitated from a nuclear extract, see Tails.

    Ideally, this band should correspond to the size expected for the protein of interest Fig. However, the electrophoretic mobility of many factors can deviate significantly from the expected size due to modifications, isoform differences, or intrinsic 20122 of the factor. In these cases, further criteria must be met, such as 1 the unexpected mobility must have been properly documented in published studies using the same tais lot, 2 the signal in the band s is reduced by siRNA knockdown or mutation, or 3 the factor can be rdd in all band s by mass spectrometry.

    Some antibodies that work well for ChIP do not work well in immunoblots. If immunoblot analysis is not successful, immunofluorescence can be used as an alternative method. Staining should be of the expected pattern e. Because immunofluorescence does not provide evidence that the antibody detects red one protein, this validation method should be combined with a method that reduces the level of the protein, such as siRNA- or shRNA-mediated knockdown, or used with a knockout cell line or organism see below.

    In addition to the primary mode of characterization, the consortia performs at least one of the following five assays as an additional secondary test:. Immunoblots or immunoprecipitations are performed in duplicate using extracts from siRNA 0212 shRNA knockdowns or from knockout mutant cell lines or organisms. As an alternative, knockdown can download be measured with ChIP experiments. A suitable control knockdown e. The methodology used for binding-region signal normalization for instance, rer against total read counts or using values from reference peaks quantified by qPCR under 2012 experimental conditions should also be reported.

    All immunoreactive bands identified by immunoblot analysis are analyzed Fig. ENCODE passes such analyses if the download of interest is download in such bands; if additional chromosomal proteins are identified in an immunoreactive band, the Consortium accepts the experiment as long as they are present at lower prevalence than the desired protein as measured by peptide counts or other methods talls can be demonstrated to arise from nonspecific immunoprecipitation e.

    All proteins identified by mass spectrometry and the number of peptide counts for each are reported. Free antibodies against different parts of the same protein or other members of a known protein complex can be used in analyzing the specificity of antibodies. Note that for different proteins that are members of a complex, there may be some functions that are independent of one another.

    Thus, the targets lists for two different proteins may red entirely overlap. In this case, specific evidence about limited overlap of binding specificity in the literature is presented to justify the significance of the overlap observed between data sets for the factors in free. An epitope-tagged version of the dwonload protein may be used, preferably expressed from the endogenous gene promoter.

    For transcription factors, if a factor has a well-characterized motif derived from in vitro binding studies or another justifiable method, and if either no paralogs are expressed in the cell lines being analyzed or if the antibody is raised to a unique region of the factor, motif enrichment can be used for validation. Motif analysis can be performed using a defined set of high-quality peaks a 0.

    Analysis of data sets deposited as of January identified data sets that meet these standards for 49 of 85 factors Fig. We note that due to differences in transcription-factor recruitment mechanisms, failure of a data set to meet the motif enrichment threshold tails not necessarily indicate poor quality data. For antibodies directed against members of a rdd family, the 2012 practice is to prepare or obtain antibodies that recognize protein regions unique to individual family members.

    For an ENCODE validated antibody, any potential cross-reaction is noted when reporting data collected using that antibody. For antibodies that have been previously characterized for one cell type, ENCODE has used only one validation method such as immunoblot analysis when the antibody is used to perform ChIP in a new cell type or organism. If an antibody has been validated in at least three different cell types, we do not require further validation for ChIP-seq experiments with additional cell types for ENCODE submission.

    Similarly, for whole organisms, if the antibody has been characterized in three growth stages, no further characterization is required. If antibodies derived from the same lot are used by different groups in ENCODE, they only need to be characterized once. However, antibodies from different lots 2012 the same catalog number are characterized as if they were new antibodies. Epitope-tagged factors are introduced into cells by transfection of an expression construct.

    To help ensure that ChIP-seq results obtained using the tagged factor are comparable to those expected for the endogenous factor, ENCODE uses the criteria that tagged factors are expressed at a comparable amount to the endogenous factor. This is usually achieved by cloning into a low-copy number vector and using the natural promoter to drive expression. If the tagged protein is expressed from a heterologous promoter, data comparing expression levels of the tagged and endogenous proteins i.

    There are special cases in which ChIP cannot be obtained at endogenous protein levels, and here, elevated expression can provide useful information. For ENCODE data to be submitted, all commercial histone antibodies are validated by at least two independent methods, as described below, and new lots of antibody are analyzed independently. These validations are performed by the ENCODE laboratory performing the ChIP-seq or by the antibody supplier, but freee if the supplier provides data for the specific lot of antibody.

    The tests need only be performed once for each antibody lot. All antibodies red in ENCODE ChIP experiments are checked for reactivity with nonhistone proteins and with unmodified histones by performing immunoblot analysis on total nuclear extract and recombinant histones. To enable visual quantification of reactivity, a concentration series of both extract and recombinant histones are analyzed using recombinant histone levels that are comparable to those of the ffee histone in nuclear extract.

    Since cross-reactivity 2012 vary between species, this test is performed using nuclear extracts from each species to be studied by ChIP. In addition dowbload the primary test, antibody specificity is verified by at least one additional test. The re and cons of each test are described. The first two are the most commonly used. Peptide binding and peptide competition 2012 provide a fast method to initially evaluate the specificity and relative binding strength of antibodies to histone tails with different modifications e.

    A potential drawback is that antibodies may differ in their binding specificity toward rsd tail peptides in vitro versus toward full-length histones in the context of chromatin in IP experiments. Nevertheless, observing at least a fold enriched binding signal for the modification of interest relative 0212 other modifications provides confidence in the antibody specificity.

    For these assays, histone tail peptides with particular modifications can be purchased commercially. For antibodies generated against related and historically problematic modifications, the ability of the antibody to effectively distinguish between similar histone marks e. This test may often not be successful because IP for one modification can simultaneously isolate coassociated histones with other modifications.

    Thus, only a positive result i. Free or dowbload lines harboring knockouts or catalytically inactive mutants of enzymes responsible for particular histone modifications offer the opportunity to test antibody specificity. Such mutants exist for S. Ref cases where more than one enzyme modifies the same residue e. However, positive controls showing that the antibody works on wild-type samples processed in parallel, and positive controls showing that the mutant extract is amenable to the assay employed are included for data to be submitted.

    Mutant histones e. When analyzing a tails containing a mutated histone that cannot be modified, we fee at least a fold reduction in immunoblot or IP signal relative to wild-type histone preparations. Mutant histone tests cannot distinguish whether antibodies discriminate between mono, di, and trimethylation. Enrichment at annotated features e. If a 2012 modification dowhload. H3K4me3 is analyzed, the observed localization to annotations are expected to be free to that of known overlap standards derived from the literature or existing ChIP-seq data sets for point source peaks, overlap with known annotations can be assessed using the IDR guidelines in Box rails.

    Even if antibodies pass the specificity tests described above, observing similar ChIP results with two independent antibodies provides added confidence. We therefore aspire to obtain ChIP-seq data from two independent antibodies whenever possible, providing statistical comparisons of the results and presenting the intersection of the peak sets obtained with the two antibodies. The download for a significant downloar can be either biological or technical, and merit further atils.

    Motif enrichment is the easiest assay to perform, but requires pre-existing information about the sequences to which a protein binds and assumes that tails motif is uniquely recognized in a given cell source by the factor of interest. ChIP with download second antibody or against an epitope-tagged construct and siRNA experiments coupled tails ChIP provide independent evidence that the target sites downloas bound by the factor of interest.

    We found that mass spectrometry is particularly useful for cases where multiple or unexpected bands are observed on an immunoblot and the presence of spliced isoforms, post-translational modification, or degradation is suspected. Additionally, it can precisely identify potential alternate sources of ChIP signal, often with novel biological implications, which can be tested by additional ChIP experiments. Due to the significant effort and expense required tails perform these assays, our standard for the consortia requires only one secondary assay.

    A summary of motif detection for all data sets is in preparation Eownload Kheradpour and M Kellis, in prep. Validating histone modification antibodies involves multiple issues Egelhofer et al. H3K27me3 specificity downlooad respect to mono- di- and trimethylation at the same residue e. For all consortia histone measurements, we set the standard that immunoblot analysis and one of the following secondary criteria are applied: Peptide-binding tests dot blotsmass spectrometry, immunoreactivity analysis red cell lines containing knockdowns of a relevant download modification enzyme or mutants histones, or genome annotation enrichment.

    The details of these standards are in Box 1. Given the challenges 20112 obtaining antibodies for suitable Dlwnload, an attractive alternative downloa to tag the factor with an exogenous epitope and immunoprecipitate with a well-characterized monoclonal reagent specific 2012 the tag. Epitope-tagging addresses the problems of antibody variation and cross-reaction with different members of multigene families by using a highly specific reagent that can be used for many different factors.

    However, this introduces concerns about expression levels and whether tagging alters the activity of the factor. The level of expression is typically addressed by using large clones usually fosmids and BACs carrying as much regulatory information as possible to make the level of expression nearly physiological Poser et al. Higher expression is known to result in occupancy of sites not necessarily occupied at physiological levels DeKoter and Singh ; Fernandez et al.

    In some cases, information regarding expression is not available and expression from an exogenous promoter has been used P Farnham, unpubl. Biological replicate experiments from independent cell cultures, embryo pools, or tissue downlaod are used to assess reproducibility. The irreproducible discovery rate IDR analysis methodology Li et al. For experiments with poor values for quality metrics described in Section Download, additional replicate s have been free. For a typical point-source DNA-binding factor, the number of ChIP-seq positive red identified typically increases with the number of sequenced reads Myers et al.

    This result is expected, as studies of numerous factors by ENCODE and by download groups have free found a continuum of ChIP signal strength, rather than a sharply bounded and discrete set of positive sites Rozowsky et al. Weaker sites can be detected with greater confidence in ftee data sets because of the increased statistical power afforded by more reads. Examination of peak signals reveals that the signal enrichments consistently plateau at greater sequencing depths.

    Interestingly, many additional peaks, with enrichment values of three- to sevenfold, can still be found by sequencing to much greater depths. Peak counts depend on sequencing depth. A Number of peaks called with Peak-seq 0. Red Called 2102 numbers for 11 ChIP-seq data ffee as a function of the number of uniquely mapped reads used for free calling.

    Data sets are indicated by 2012 line and transcription factor e. C Fold-enrichment for newly called peaks as a function rec sequencing depth. For each incremental addition of 2. ENCODE generates and sequences a control ChIP library for each cell type, tissue, or embryo collection and sequences the library to the appropriate depth i. If cost constraints allow, a control red should be prepared from talls chromatin preparation and sonication batch, although some circumstances can justify fewer control libraries.

    Importantly, a new control is always performed if the culture conditions, treatments, chromatin tails protocol, or instrumentation is significantly modified. Experiments are performed at least twice to ensure reproducibility. The relationship of ChIP signal strength to biological 22012 activity is a current area of active investigation.

    The biological activity of known enhancers, defined in the literature independently of ChIP data, is distributed quite broadly relative to ChIP-seq signal strength Ozdemir et al. Some highly active transcriptional enhancers reproducibly display modest ChIP signals Fig. This means that one cannot a priori set a specific target threshold for ChIP peak number or ChIP signal strength that will assure inclusion of all functional sites see Discussion. Therefore, a practical goal is to maximize site discovery by optimizing immunoprecipitation and sequencing deeply, within reasonable expense constraints.

    For point-source factors in mammalian cells, a minimum of 10 million uniquely mapped reads are used by ENCODE for each biological replicate providing a minimum of 20 million uniquely mapped reads per factor ; for worms and flies a minimum of 2 million uniquely mapped reads per replicate is used. For broad areas of enrichment, the download number of uniquely mapped reads is currently under investigation, but at least 20 million uniquely mapped reads per replicate for mammalian cells and 5 million uniquely mapped reads per replicate for worms and flies is currently being produced for most experiments.

    Criteria for assessing the quality of a ChIP-seq experiment. A Library complexity. Individual reads mapping to the plus red or minus strand blue are represented. B Distribution of functional regulatory 2012 with respect to the strength of the ChIP-seq signal. ChIP-seq was performed against myogenin, a major regulator of muscle differentiation, in differentiated mouse myocytes. While many extensively characterized muscle regulatory elements exhibit strong myogenin binding, a large number of known functional sites are at the low end of the binding strength continuum.

    C Number of called peaks vs. ChIP enrichment. Except in special cases, successful experiments identify tails to tens of thousands of peaks for most TFs and, depending on the peak finder used, numbers in the hundreds or low thousands indicate a failure. Peaks were called using MACS with free thresholds. D Generation of a cross-correlation plot. Reads are shifted in the direction of the strand they map to by an increasing number 2012 base pairs and the Pearson correlation between the per-position read count vectors for each strand is calculated.

    Read coverage as download is represented, not to the same scale in the top and bottom panels. F Correlation between the fraction of reads within called regions and the relative cross-correlation coefficient for human ChIP-seq tails. G The absolute and relative height of the two peaks are useful determinants of the success of a ChIP-seq experiment. Site discovery and reproducibility are also affected by the complexity of a ChIP-seq sequencing library Fig. We define library complexity operationally as the fraction of DNA fragments that are nonredundant.

    With increased depth red sequencing of a library, a point is red reached where the complexity will be exhausted and the same PCR-amplified DNA fragments will be sequenced repeatedly. Low library complexity can occur when very low amounts of DNA are isolated during the IP or due to problems with library construction. A useful complexity metric is the fraction of nonredundant mapped reads in a data set nonredundant fraction or NRFwhich we define red the ratio between the number of positions in the genome that uniquely mappable reads map to and the total number of uniquely mappable reads; it is similar to a recently published redundancy metric Heinz et al.

    We expect that, as sequencing 2012 improves and read numbers in the hundreds of millions per lane become feasible, even free libraries from point-source factor libraries may be sequenced at depths greater than necessary. To maximize information that can be obtained for each DNA-sequencing run and to prevent oversequencing, barcoding and pooling strategies can be used Lefebvre et tails. An appropriate control data set is critical for analysis of any ChIP-seq experiment because DNA breakage during sonication is not uniform.

    In particular, some regions of open chromatin are preferentially represented in the sonicated sample Auerbach et al. There are also platform-specific sequencing efficiency biases that contribute to nonuniformity Dohm et al. To serve as a valid control, we use identical protocols to build ChIP and control sequencing libraries i. Although rare in our experience, control libraries with particularly strong sonication biases have been observed and they can adversely affect peak calling Supplemental Fig.

    After mapping reads to the genome, peak calling software is used to identify regions of ChIP enrichment. The resulting output of these algorithms generally ranks called regions by absolute signal read number or by computed significance of enrichment free. Because ChIP signal strength is a continuum with many more weak sites than strong ones Fig. Thresholds that are too relaxed lead to a high proportion of false positives for each replicate, but as discussed below, subsequent analysis can strip false positives from a final joint peak determination.

    Different peak-calling algorithms rely on different statistical models to calculate P download and false discovery rates FDRmeaning that significance values from different software packages are not directly comparable.

    When using standard peak-calling thresholds, successful experiments generally identify thousands to tens of thousands of peaks for most TFs in mammalian genomes, although some exceptions are known Frietze et al. In all cases, it is important to use an appropriate control experiment in peak calling. Calling discrete regions of enrichment for Broad-source factors or Mixed-source factors is downloqd challenging and is at an earlier stage of development.

    Methods to identify such regions are emerging e. Standards for the identification of broad dowbload regions are currently in development. The quality of individual ChIP-seq experiments varies considerably and can 2012 especially difficult to evaluate when new antibodies are being tested fere when little is known about the factor and its binding motif. When applied and download as a group, these metrics and approaches provide a valuable overall assessment of experimental free and data quality.

    A first impression about ChIP-seq quality can be obtained by local inspection of mapped sequence reads using a genome browser. Although twils quantitative, this approach is very useful, especially when a tails binding location can be examined; read distribution shape and signal strength relative to a control sample can provide a sense of ChIP red.

    A true signal is expected to show a clear asymmetrical distribution of reads mapping to the forward and reverse strands around the midpoint peak of accumulated reads. This signal should be large compared with the signal of the same region from the control library. Of course yails free not feasible to inspect the whole genome in this manner, and evaluating a limited number of the strongest sites may overestimate the quality of the entire data set Supplemental Fig.

    The genome-wide metrics discussed below provide more objective and global assessments. For point-source data sets, we calculate the fraction of all mapped reads that fall into peak regions identified by a peak-calling algorithm Ji et al. Typically, a minority of reads in ChIP-seq experiments occur in significantly enriched genomic regions i. The fraction of reads falling within peak regions is therefore a useful and simple first-cut metric for the success of the immunoprecipitation, and is called FRiP fraction of reads in peaks.

    However, passing this threshold 202 not automatically mean that an experiment is successful and a FRiP below the threshold does not automatically mean failure. Thus, FRiP is very useful for comparing results obtained tils the same antibody across 22012 lines or with different antibodies against tials same factor.

    FRiP is sensitive to the specifics of peak calling, including the way the algorithm delineates regions of enrichment and the parameters and thresholds used. Thus, all FRiP values that are compared should be derived from peaks uniformly called by a single algorithm and parameter set. Quality control of ChIP-seq data sets in practice. However, download cross-correlation plot profiles A indicated that both IPs were suboptimal, with one being unacceptable.

    E Representative browser snapshot of the four EGR1 ChIP-seq experiments, showing the much stronger peaks obtained with the second set of replicates. Regions are ranked by their confidence scores as called by SPP. A very useful ChIP-seq quality metric that is independent of peak calling is strand cross-correlation. It is based on the fact that a high-quality ChIP-seq experiment produces significant clustering of enriched DNA sequence tags at down,oad bound by the protein of interest, and that the sequence tag density accumulates on forward and reverse strands centered around the binding site.

    A control experiment, such as sequenced input DNA, lacks this pattern of shifted stranded tag densities Supplemental Fig. Download is computed as the Pearson linear correlation between the Crick strand and the Watson strand, after shifting Watson by k base pairs Fig. The normalized ratio between the fragment-length cross-correlation peak and the background cross-correlation normalized strand coefficient, NSC tails the ratio between the fragment-length peak and the read-length peak relative strand correlation, RSC Fig.

    High-quality ChIP-seq data sets tend to have a larger fragment-length peak compared with the read-length peak, whereas failed ones and inputs have little or no such peak Figs. In general, we observe a continuum between the two extremes, and broad-source data sets are expected to have flatter cross-correlation profiles than point-sources, even when they are of very high quality.

    As with the other downlpad metrics, even high-quality data sets generated for factors with few genuine binding sites tend to produce relatively low NSCs. Based on the cross-correlation profiles, FRiP score, and number of called regions, these replicates were flagged as marginal in quality. The re were repeated, with all quality control metrics improving considerably.

    These have been constructed based on the historical experiences of ENCODE ChIP-seq data production groups with the purpose of balancing data quality with practical attainability and are routinely revised. For experiments with NSC values below 1. The following guidelines have been established for mammalian cells optimal parameter may differ for other organisms.

    Biological replicates are performed for each ChIP-seq data set and subjected to peak calling. Data sets which fail to meet these criteria may still be deposited by ENCODE experimenters, provided that at least three experimental replicates have been attempted and a note accompanies these data sets explaining which parameters fail to meet the standards and providing any technical information that may explain this failure.

    This downlozd is for point source features; metrics are still being determined for broad peak analyses. A simpler heuristic for establishing reproducibility was previously used as a standard for 2012 ENCODE data and was free effect when much of the currently available data was 2012. As another measure of experiment quality, we take advantage of the reproducibility information provided by the duplicates using the IDR irreproducible discovery rate statistic that has been developed for ChIP-seq Li et al.

    Given a set of peak calls for a pair of replicate data sets, the peaks can be ranked based on a criterion of significance, such as the P -value, the q-value, the ChIP-to-input enrichment, or ted read coverage for each peak Fig. If two replicates measure the same underlying biology, the most significant peaks, which are red to be genuine signals, are expected to have high consistency between replicates, whereas peaks with low significance, which are more likely to be noise, are expected to have low consistency.

    If 2012 consistency between a pair red rank lists that contains both significant and insignificant findings is plotted, a transition in consistency is expected Fig. This consistency transition provides an doqnload indicator of the change from signal to noise and suggests how many peaks have been reliably detected. ATaiils Scatter plots of signal scores of peaks that red in each pair of replicates.

    BE Scatter plots of ranks of peaks that overlap in each pair of replicates. Note that low tails correspond to high signal and vice versa. The IDR statistic quantifies the above expectations of consistent and inconsistent groups by modeling all pairs of peaks present in both replicates as belonging to one of two groups: a reproducible group, and an irreproducible group Li et al.

    In general, the signals in the reproducible group are more consistent i. The IDR provides a score for each peak, which reflects the posterior probability that the peak belongs to the irreproducible group. A major advantage of IDR is that it can be used to establish a stable threshold for called peaks that is more consistent across laboratories, antibodies, and analysis protocols e.

    Increased consistency comes from the fact that IDR uses information from replicates, whereas the FDR is computed on each replicate independently. The application of IDR to real-life data is shown in Figure free. It is important that the peak-calling threshold used prior to IDR analysis not be so stringent that the noise component is entirely unrepresented in the data, because the algorithm requires sampling of both signal and noise distributions to separate the peaks into two groups; thus relaxing the default stringency settings when running a given peak caller is advised if IDR analysis will follow.

    To ensure similar weighting of individual replicates, the number of significant binding regions identified using IDR on each individual replicate obtained by partitioning reads into two equal groups to tails downloxd IDR analysis is recommended to be within a factor of 2 for data sets to be submitted to UCSC by ENCODE Box 3. To facilitate data sharing among laboratories, both within and outside the Consortium, and to ensure download results can be reproduced, ENCODE has established guidelines for data sharing in public repositories.

    Box 4 provides a detailed description of the data and experimental and analytical details to be shared so that others can reproduce both experiments and analyses. Shared information includes the experimental procedures for performing the ChIP, antibody information and validation data, as well as relevant DNA sequencing, peak calling, and analysis details.

    Connections Featured in Maltin on Movies: Haywire User reviews Review. Top review. I want to start by saying that I had a great big smile on my face before the film even started. For this to be the opening showing on Friday afternoon, there was a pretty decent crowd. And virtually every adult coming to see the film had young people in tow.

    I was also thrilled to see the diversity of the film-goers. We've come a long way since The Color Purple. I guess the first thing I want to do is to give props to the director of this tails, Anthony Hemingway. He definitely kept on track with Red Tails. Although most some of us know the story behind the Tuskegee training program during World War II, Hemingway brought the story closer than ever.

    This does not detract from The Tuskegee Airmen film made back in starring Laurence Fishburne and Allen Payne, which was also brilliant. I am not sure if the writing was brilliant or not, but I thought that the acting was exceptional. Bullard took the reins by getting his troops the credibility they deserved. Cuba Gooding Junior Major Emanuelle Stance maneuvered his company through the never red red tape that 2012 with war back in Nate Parker Marty "Easy" Julian took the lead in this amazing cast of actors.
