Figure 2

Cell survival experiments represent relative survival of PC3, LNCaP, and DU145 cell lines after 24 hr exposure to VP16 etoposide at various concentrations (2A). One dimensional histograms show relative number of cells (vertical axis) for fluorescent intensities over a 4 log unit range (bottom horizontal axis) using a 256 channel A/D converter (top horizontal axis). Sample histograms are shown for the following conditions: control PC3 cells (2B), 24 hr treatment with 10 nM taxotere (2C), same with 50 nM taxotere (2D). At bottom, bar graph (2E) shows the dynamic range of the mean fluorescence intensity normalized to an arbitrary control value of 1.0 on a linear scale. Cell counts appeared at values over the entire 4 log unit range.
