After 48 h, ChIP assays were performed using the ChIP-IT express chromatin immunoprecipitation kit (Active Motif) with FLAG antibodies. HPV-18 LCR DNA was amplified using RT-PCR, and values were normalized to those of input DNA. Control = no FLAG E2 DNA; WT = 1. Values are expressed as means ± SEM. *, P ≤ 0.05 by two-tailed t test compared to control. (B) HeLa cells were transfected with FLAG-HPV-31 E1 and FLAG-WT or Y138 E2 mutants. After 48 h, the ChIP assays were performed with rat anti-E1 antibodies. HPV-18 LCR DNA was amplified using RT-PCR, and values were normalized to those of input DNA. No E1 = 1.
