The chromatin was then fragmented to ~500bp by sonication and the lysate was incubated with the anti-Flag M2 Magnetic beads (Sigma, Cat# M8823) at 4°C for 2h. The beads were washed 5 times, for 5min at 4°C and then the crosslinking was reversed by incubation at 65°C overnight and further purified using the phenol:Chloroform:Isoamyl Alcohol kit (Thermo scientific, Cat# 17908). The resulting DNA then was used for library preparation with NEBNext Ultra II DNA Library Prep Kit (NEB, Cat# 7645). The ChIP libraries were sequenced in SE50 mode on a HiSeq2500 machine.
