library_construction_protocol: Cells were fixed with 1% formaldehyde for 10 minutes. After quenching and cell lysis, chromatin was sonicated using diagenode Bioruptor 300. Chromatin was incubated with H3K27me3 antibody (Active Motif AB_2561020). Immunoprecipitation was done using Pierce ChIP-grade Protein A magnetic beads. Library was prepared using IonTorrent Ion Plus Fragment Library Kit
