Percent of apoptotic cells versus time as a function of gemcitabine concentration. Cells were exposed to the indicated concentration of gemcitabine starting at 0 h. Apoptosis was determined at each time point based upon the fraction of cells in subG1 phase, as determined by flow cytometry. a AsPC-1, b BxPC-3, and c MiaPaca-2 cells
