WebWe don't always do this for ChIP-qPCR but we always do this if we're going to ChIP-seq the samples. At that Gapdh promoter input is ct 26-27, PolII is 27-28, which works out to PolII being enriched to about 2% the level of input. At the Bactin promoter I get about 3.5% input. IgG is basically undetectable by 35 cycles.
