ChIP-seq for H3K4me3 in control K562 (NT1)
"ChIP samples for H3K4me3 were prepared by MNase digestion and sonication of chromatin to achieve DNA fragmentation, followed by immunoprecipitation using H3K4me3 antibody (Cell Signaling Technology #9751), and adapter ligation and PCR amplification using NEBNext Ultra II DNA Library Prep Kit for Illumina (New England Biolabs #E7645), according to the manufacturer's protocol."
