Cells were fixed with 1% formaldehyde for 10 minutes at room temperature before termination with 0.125 M glycine. Cells were then lysed in ChIP buffer (0.6% SDS, 10 mM EDTA, and 50 mM Tris-HCl, pH 8.1) and cross-linked chromatin was sonicated to obtain DNA fragments of 300–800 bp. Immunoprecipitations were performed following the Upstate protocol (http://www.upstate.com). DNA was recovered by phenol-chloroform extraction and ethanol precipitation. ChIP-seq libraries were prepared using NEBNext DNA library preparation reagents (E6000) and the protocol and reagents concentrations described in the Illumina Multiplex ChIP-seq DNA sample Prep Kit. Libraries were indexed using a single indexed PCR primer. After PCR amplification, 300-600 bp DNA fragments were selected on an agarose gel. Libraries were quantified by Qubit (Invitrogen), and library size was assessed by Bioanalyzer (Agilent). Libraries were sequenced using a HiSeq 2000 (Illumina) to generate 50 bp single end reads.
