FIG. 3.

Histone acetylation and methylation at the TNF-α locus. These results represent an average of duplicates or triplicates of two to three separate experiments. The normalized units represent the signal from the immunoprecipitate normalized to 10% of the original input DNA. (A) Schematic representation of the primers and probes used for real-time PCR quantitation. (B) Graphical representation of ChIP analyses. AcH3, acetylated H3; AcH4, acetylated H4; H3 Dimeth, H3K4 dimethylation; H3 Trimeth, H3K4 trimethylated. (C) Total H3 ChIP.
