library_construction_protocol: Cell were fixed with 1% formaldehyde for 15 min. After quenching and cell lysis, chromatin was sonicated using BioRaptor II (BM Equipment Co.). ChIP-seq libraries were prepared using the KAPA HTP Library Preparation Kit. 10 ng of DNA was used as starting material for Input and ChIP samples. Libraries were amplified using 13 cycles on the thermocycler. Post amplification libraries were size selected at 250-450 bp in length using Agencourt AMPure XP beads from Beckman Coulter. Libraries were validated using Tapestation.
