ChIP was performed as previously described (Lee et al., 2006) ChIP-seq libraries were prepared using NEBNext Ultra DNA Library Prep Kit for Illumina (E7370) and NEBNext Multiplex Oligos for Illumina (E7335) according to the manufacturer’s protocol. Massively parallel sequencing was performed with the Platform: Nextseq 500. Flow cell was Nextseq 500/550 High Output Flow Cell Cartridge V2, reagent was Nextseq 500/550 V2 75 cycles.
