Lysates were clarified from sonicated nuclei and protein-DNA complexes were precipitated with antibody. ChIP-seq library preparation was performed using TruSeqChIP Sample Prep Kit (Illumina) according to the manufacturer's instructions.10ng of input ChIP-enriched DNA was used for ChIP-seq library preparation. Final libraries were checked using High Sensitivity chips in 2100 Bioanalyzer (Agilent). Average fragment size of final libraries was found to be 280 ± 8bp. Paired-end sequencing (2 x 100 bp) of these libraries were performed in HiSeq-2500 (Illumina) according to the manufacturer's protocols.
