title: GSM3177720: NPC_H3K27AC; Homo sapiens; ChIP-Seq
library_construction_protocol: For Hi-C, nuclei were extraced after fixing using a cell lysis buffer. For ChIP-seq, nuclei were extracted and chromatins were fragmented by sonication. The TF/histone-DNA complexes were isolated by antibody. All Hi-C libraries were constructed following illumina insctructions accompanying Truseq sample preparation kit.  Random indexes were introduced for eHi-C libraries to remove PCR duplication. Generally, PCR amplification was done with 7-9 cycles. All ChIP-seq libraries were generated following a ChIPmentation protocol with Nextera adapters.
