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
