title: GSM6665997: Treated3_00251766_HDAC1; Homo sapiens; ChIP-Seq
library_construction_protocol: Cells were fixed with 1% formaldehyde for 15 min and quenched with 0.125 M glycine. 15 ug of chromatin was immunoprecipitated per sample using antibodies against HDAC1 (Active Motif # 40967) and BRD4 (Active Motif # 91301, 4l), H3K9Ac (Active Motif # 39917), H3K27Ac (Active Motif # 39133), and RNA Pol II (Active Motif # 91151), Illumina sequencing libraries were prepared from the ChIP and input DNAs by the standard consecutive enzymatic steps of end-polishing, dA addition, and adaptor ligation. After a final PCR amplification step, the resulting DNA libraries were quantified and sequenced on Illumina's NextSeq 500.
