Figure 5.

Reversal of targeted histone acetylation upon dissociation of TetR–VP16 from the UGT51promoter . Samples used in Figure 4 were analyzed by quantitative duplex PCR using UGT51 primers instead of HIS3 primers. After normalizing each IP signal to the input signal, the UGT51 results were divided by the those of the control locus, and expressed relative to the 4-hour-treated sample.
