Hierarchical clustering of all data points (ΔCt) from 4 separate siRNA screen experiments outlining effects of 240 siRNA genes on loss (+ΔCt, red) or gain (−ΔCt, blue) of episomes in the absence of PA25.

<p>All genes are aligned on the y-axis (left). The columns represent experiments conducted on days 1−3 (cells maintaining HPV16) and day 4 (cells maintaining HPV31).
