library_construction_protocol: 10×106 cells were cross-linked by 2% formaldehyde for 10 min and 0.125 M glycine was added to prevent further cross-linking. Cells were collected and washed with 14 ml PBS twice, then cells were centrifuged and suspended in lysis buffer to disrupt membranes and isolate chromatin. A primary 6-base cutter, 400 U HindⅢ was used for the first digestion at 37°C with shaking overnight followed by diluted ligations. After precipitation, chromatin was further subjected to a second round of digestions with a 4-base cutter Dpn Ⅱ and ligation. Primers for the c-myb viewpoint (forward, AGTATTAATTTGCC-TTGTCC; reverse, GCTAATGTTGGATATATTGC) were designed. Inverse polymerase chain reaction (PCR) was carried out to amplify sample libraries. Libraries were pooled and sequenced using the Illumina HiSeq machine as 150-bp paire-end sequencing reads.
