Figure 2. The TATA binding protein (TBP) and RNA Polymerase II (RNAP) associate with the ß-catenin/TCF4 enhancers in HCT116 cells.

Figure 2

(A) Real-time PCR analysis of ChIP assays conducted in HCT116 (black bars) or HEK293 cells (gray bars) using specific antibodies against TATA binding protein (TBP). Data is represented as fold binding over control (Ctl.). (B) As in A, except that antibodies specific for RNAP phosphorylated on serine 5 of its carboxy-terminal domain were used in the ChIP assays. (C) As in A and B except antibodies that detect total RNAP were used in the ChIP assays. In each experiment, error bars represent SEM.
