Sulfyhydryl-Reactive Site-Directed Cross-Linking as a Method for Probing the Tetrameric Structure of Histones H3 and H4

is site-directed cross-linking. Here, through the introduction of cysteine residues at strategic locations in histone proteins, we use site-directed cross-linking to monitor the association of chromatin subunits. This approach is informative for the study

RNA-biotin based pulldown assays for the detection of siRNA targeted genomic regions and siRNA directed histone modifications (PROT32)

upon the dual pulldown to incorporate a third pulldown which is an iteration of the ChIP and is a pulldown for H3K27me3+ (Figure 1b). The third assay described here is the biotin-RNA pulldown of a low-copy RNA that spans the siRNA targeted promoter region

做好 ChIP 的四个注意事项

实际上将作为阴性对照使用。CST 推荐使用 Histone H3 (D2B12) XP® Rabbit mAb (ChIP Formulated) #4620。该抗体可检测与基因组中所有 DNA 序列结合的所有组蛋白 H3 类型（H3、H3.3、CENP-A）。因此，不管检测的位点活性状态如何，该抗体都能为 ChIP 实验提供通用的阳性对照。 阴性对照 阴性对照抗体（如正常兔 IgG）不能识别特异抗原表位，因此可用于检测非特异性结合。例如，如果阴性对照样品中的产物量等于特异
