【Abstract】 HL 60 cells induced by camptothecin were treated with hypertonic phosphate citric acid buffer, and the DNA content was detected by using linear and logarithmic amplifier simultaneously. The results showed that the sub G 1 peak of apoptotic cells and the peak of necrotic cells could be separated efficiently, but the linearity between the DNA content of G 1 cells and G 2 cells wasn’t affected. It was suggested that flow cytometric DNA content analysis was a major method for cell biological and clinical analysis.更多还原
