BRD4 N-terminal antibody (Wu at al., 2006) (4 µl used)
Sequenced DNA Library
Cells were crosslinked with 1% Formaldehyde for 10 or 20 minutes and quenched with 125 mM Glycine. The nuclear pellets were sonicated to the fragment range of 200-400 bp. Sonicated extracts were incubated with specific antibodies at 4˚C overnight and ChIP-immune complexes were pulled down using Protein A sepharose. Library preparations were done using NEBnext Ultra DNA library preparation kit according to the manufacturer's instructions.
