Chromatin samples were incubated with specific antibodies in the ChIP Lysis buffer (20 mM Tris-HCl pH8.1, 150 mM NaCl, 2 mM EDTA, 1% TritonX-100 and 0.05% SDS) overnight at 4℃. The protein-DNA complexes were immobilized on pre-washed protein A/G beads (20μl per reaction). The bound fractions were washed 3 times with the Lysis buffer, and twice with the Low Salt Wash buffer (10 mM Tris-HCl, 250 mM LiCl, 1 mM EDTA, 0.5% NP-40, 0.5% Na-deoxylcholate), and once with 10 mM Tris-HCl pH8.0. Elution and reverse crosslinking were carried out in the Elution buffer (50 mM Tris-HCl pH8.0, and 1% SDS) at 65℃ for 5 hours. After 1 hour of RNase A (1unit/μl) at 37℃ and Proteinase K (1unit/μl) digestion at 55℃, DNA samples were then purified using PCR extraction kit (QIAGEN #28006). The precipitated DNA samples were prepared for DNA deep sequencing according to manufacturer's guidelines (SWIFT, #21096).
