title: H3K27me3 ChIP-seq of Kh1ES1: day 0 replicate 1
design: ChIP-seq was performed by fixing cells with 1% formaldehyde, followed by lysis and fragmentation by Branson sonicator. Fragmented DNA was incubated with target antibody overnight. After de-crosslinking, ChIP DNA was purified and library was constructed by Thruplex DNA-seq.
