Cells were fixed with 1% formaldehyde for 15 minutes. After quenching and cell lysis, chromatin was sonicated using a E220 focused-ultrasonicator (Covaris). ChIP-seq libraries were prepared using the NEBNext ChIP-seq Library Prep Master Mix Set for Illumina (NEB catalogue number E6240L) and then run on the Illumina sequencer HiSeq 2500. 10 ng of DNA was used as starting material for input and ip samples. Libraries were amplified using 13 cycles on the thermocycler. Post amplification libraries were size selected at 250-450bp in length using Agencourt AMPure XP beads from Beckman Coulter. Libraries were validated using the Agilent High Sensitivity DNA Kit.
