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

1a).Part II Triple immunoprecipitation: H3K27 ChIP/-flag-DNMT3A/biotin-RNA A total of 4.0×106 293T cells are plated out and 24 hours later transfected plated (~70% confluent at the time of transfection) with the flag-tagged protein expressing plasmid

Chemotaxis Assay Using Microchemotaxis Chambers (Modified Boyden Chamber)

. Do not tighten excessively. 7. Add 50 μl of the cells suspended in Chemotaxis Buffer to each well on the upper chamber. To avoid creating bubbles, touch the pipette tip to the side of the chamber (don't touch the filter) and expel the cells
