Cells with altered DNA content are identified by staining alcohol-fixed, RNAase treated cells with the intercalating dye, PI. The first peak on the left represents normal diploid cells. The next major peak represents tumor cells with increased DNA content and DNA index of 1.58. Combined with an additional fluorescent antibody specific for a unique cell population, this technique is even more powerful and allows the more accurate S phase analysis of muliple overlapping populations.
