Cells were trypsinized and re-suspended with PBS to a final concentration of 8x106 cells/ 500 μl PBS. Cell suspensions were crosslinked with 1.5mM DSG (disuccinimidyl glutarate, Thermo, #20593) for 45' at room temperature with gentle rotation. After two washes with 500 μl PBS, cell pellets were re-suspended in 1ml PBS and 1% formaldehyde was added for 10' at room temperature. Cross-linking was quenched with 125mM glycine and after two times ice-cold PBS washes, pellets were resuspended in 270 μl lysis buffer (50mM Tris pH8.0, 1%SDS, 10mMEDTA protease inhibitor) and incubated 5' on ice. Sonication was performed for 15'-20' with Bioruptor sonicator (NGS, Diagenode) and lysates were centrifuged at 13000rpm 4°C, for 5min. 5-10 ng DNA was subjected to end repair using Klenow DNA polymerase, T4 ligase and T4 polynucleotide kinase (T4 PNK). A 3′ protruding A base was generated using Taq polymerase and NEXTflex adapters were ligated. The DNA was subjected to 4 cycles PCR amplification using Kappa polymerase and purified DNA was loaded on E-gel for size selection (300 bp). The DNA was isolated, further amplified by PCR and used for cluster generation on the HiSeq2000 genome analyzer
