Figure 2.

Correlation of ChIP enrichment using either anti-Su(Hw) on wild-type chromatin or anti-GFP on chromatin from Su(Hw)-GFP transgenic. The enrichment values are plotted as the arsinh transformation (approximately equivalent to the log2 scale) of the ratio of specific versus control ChIP. Correlation coefficient is 0.66. ChIP, chromatin immunoprecipitation; GFP, green fluorescent protein; Su(Hw), Suppressor of Hairy-wing.
