        <LIBRARY_CONSTRUCTION_PROTOCOL>Cells were fixed with 1% formaldehyde for 15 min and quenched with 0.125 M glycine.  Chromatin was isolated by the addition of lysis buffer, followed by disruption with a Dounce homogenizer. Lysates were sonicated and the DNA sheared to an average length of 300-500 bp. Genomic DNA (Input) was prepared by treating aliquots of chromatin with RNase, proteinase K and heat for de-crosslinking, followed by ethanol precipitation. Pellets were resuspended and the resulting DNA was quantified on a NanoDrop spectrophotometer. For each ChIP reaction, 30 ug of chromatin was precleared with protein A agarose beads (Invitrogen). ChIP reactions were set up using precleared chromatin and antibodies and incubated overnight at 4 C. Protein A agarose beads were added and incubation at 4 C was continued for another 3 hr. Immune complexes were washed, eluted from the beads with SDS buffer, and subjected to RNase and proteinase K treatment. Crosslinks were reversed by incubation overnight at 65 C, and ChIP DNA was purified by phenol-chloroform extraction and ethanol precipitation. Illumina sequencing libraries were prepared from the ChIP and Input DNAs by the standard consecutive enzymatic steps of end-polishing, dA-addition, and adaptor ligation. After a final PCR amplification step, the resulting DNA libraries were quantified and sequenced on HiSeq 2500 (50 nt reads, single end).</LIBRARY_CONSTRUCTION_PROTOCOL>

        <LIBRARY_CONSTRUCTION_PROTOCOL>Cells were fixed with 1% formaldehyde for 15 min and quenched with 0.125 M glycine.  Chromatin was isolated by the addition of lysis buffer, followed by disruption with a Dounce homogenizer. Lysates were sonicated and the DNA sheared to an average length of 300-500 bp. Genomic DNA (Input) was prepared by treating aliquots of chromatin with RNase, proteinase K and heat for de-crosslinking, followed by ethanol precipitation. Pellets were resuspended and the resulting DNA was quantified on a NanoDrop spectrophotometer. For each ChIP reaction, 30 ug of chromatin was precleared with protein A agarose beads (Invitrogen). ChIP reactions were set up using precleared chromatin and antibodies and incubated overnight at 4 C. Protein A agarose beads were added and incubation at 4 C was continued for another 3 hr. Immune complexes were washed, eluted from the beads with SDS buffer, and subjected to RNase and proteinase K treatment. Crosslinks were reversed by incubation overnight at 65 C, and ChIP DNA was purified by phenol-chloroform extraction and ethanol precipitation. Illumina sequencing libraries were prepared from the ChIP and Input DNAs by the standard consecutive enzymatic steps of end-polishing, dA-addition, and adaptor ligation. After a final PCR amplification step, the resulting DNA libraries were quantified and sequenced on HiSeq 2500 (50 nt reads, single end).</LIBRARY_CONSTRUCTION_PROTOCOL>
