Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 10 6 HeLa cells heat shocked for 1 hr and either 10 µl of EAF2 (E1R8C) Rabbit mAb or 2 µl of Normal Rabbit IgG #2729 using SimpleChIP ® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using human c-Myc intron 1 primers, SimpleChIP ® Human HSP70 Intron 1 Primers #14023, and SimpleChIP ® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.
