ChIP was performed as described previously31 (link)using SREBP1 antibody (Santa Cruz, sc-367x). Briefly, 5 μg rabbit IgG (Santa Cruz) or SREBP1 antibody was incubated with Protein A Dynabead magnetic beads (Invitrogen) for 4 h, followed by extensive washing to remove unbound antibody. Antibody beads were then added to the chromatin and incubated overnight. The ChIP primers were purchased from Qiagen (EpiTect ChIP PCR assay) and used for qPCR analysis: BCAT2 (GPH1020848(+)03A).
