STAT1 and IRF1 binding patterns. Arbitrarily selected ChIP-chip STAT1 (n = 22), IRF1 (n = 24) sites were re-examined by ChIP-qPCR on chromatin from HeLa cells with no or 6 h of IFNγ treatment. 91% of peaks were validated in both cases. The frequency of consensus motifs identified by JASPER within STAT1 (GAS) or IRF1 (IRF-E) peaks is indicated
