Cells were crosslinked with 1% formaldehyde in culture medium for 10 minutes at room temperature. Cells were then lysed in 10 ml lysis buffer (0.1%SDS, 1% Triton X-100, 2mM EDTA, 20mM Tris-HCl ph 8.0 and 150 mM NaCl) and chromatin was sheared to 200-600 bp fragments using a Bioruptor Sonicator (Diagenode). Chromatin extract from 5x10^7 cells was incubated overnight at 4oC with 100 ul of Dynabeads Protein G magnetic beads (Life Technologies, 10004D) previously incubated with 10 ug of selected antibodies. After ChIP, samples were washed and bound complex were reversed cross-linked and eluted in 10mM Tris-HCl pH 8 The TruSeq DNA sample prep kit with indexing adapters was used according to the manufacturer's recommendations (Illumina)
