title: GSM6460432: KARPAS-422, DMSO, BRD4, replica 2; Homo sapiens; ChIP-Seq
library_construction_protocol: Cells were fixed with 1% formaldehyde for 12 minutes. After quenching with 125 M glycine and cell lysis, chromatin was sonicated using a E220 focused-ultrasonicator (Covaris). The sequencing libraries were prepared using NEBNext Ultra II DNA kit (#E7645S)
