Antibodies were used to perform ChIP and resulting chromatin fragments were used to prepare deep sequencing libraries. Please see treatment protocol for antibodies used. Libraries were prepared with NEBNext ChIP-Seq Sample Prep Master Mix Set 1 (NEB# E6240S) which provides in-line barcodes and libraries were sequenced with Illumina HiSeq 2000. Single-end sequencing of reads were up to 50 bases.
