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

by adding 1µl Rnase A (10mg/ml) and 20µl of 5M NaCl. Incubate the samples in a 65° water bath or heat block for 4-5 hours to overnight (note 5); ;After the reverse cross-linking the elutes are treated with 10µl of 0.5M EDTA, 20µl of 1M Tris-HCL, pH
