Equivalent regions set through S phase.

<p>DNA histograms from K562 cells stained for single cyclins A2 (B) or B1 (C) or stained for both cyclin A2, B1, and PHH3 (A) were transformed by functions denoted on the X axes to place the mode of G1 in channel 350 and the mode of G2 in channel 700. Each histogram was then segmented with 6 equally sized regions that expanded out from a middle point. The median values for cyclin A2 and B1 were calculated from measurements gated on these regions. These values were then used to construct the plots in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0038275#pone-0038275-g007" target="_blank"><b>Figure 7A, 7B</b></a>.
