Chromatin was fixed in 1% formaldehyde for 10 minutes, sheared to 200-700bp using a Bioruptor (Diagenode), immunoprecipitated using the indicated antisera, purified and sequenced using HiSeq 2000 as recommended by the manufacturer. DNaseI treatment was done on isolated nuclei for 3 minutes and reaction was stopped with stop buffer ( 50mM Tris-HCl, pH 8, 100mM NaCl, 0.10% SDS, 100mM EDTA, pH 8.0, 1mM Spermidine, 0.3mM Spermine), sample was further fractionated on 9% Sucrose gradient for  24hrs/25000rpm at 16ºC . Further sequenced using HiSeq as recommended by the manufacturer.
