Chromatin fixation and immunoprecipitation were performed essentially as described in Orlando et al. (1997; PMID:8993033). Cells (3-4x108) were fixed in 200 mL of medium with 1% formaldehyde for 10 min at room temperature. Cross-linked cells were sonicated to produce chromatin fragments of an average size of 150–400 bp. Soluble chromatin was separated from insoluble material by centrifugation. The supernatant containing chromatin of 1-2x107 cells was used for immunoprecipitation. Sequencing libraries were prepared with the NEB Genomic DNA Sample Preparation Kit according to NEB’s instructions. After adapter ligation, library fragments of 250-350 bp were isolated from an agarose gel. The DNA was PCR amplified with Illumina primers with 18 cycles, purified, and loaded on an Illumina flow cell for cluster generation. Libraries were sequenced on the Genome Analyzer IIx (TrueSeq cBot-GA v2 and TruSeq v5 SBS kit) and HiSeq 2000 (HiSeq Flow Cell v3 and TruSeq SBS Kit v3) following the manufacturer’s protocols.
