Abstract:

7-Aminoactinomycin D (7-AAD) is a DNA dye that distinguishes viable, apoptotic, and late apoptotic/dead cells in flow cytometry. Several staining protocols using 7-AAD have been described, but data on the influence of the 7-AAD concentration on the readout are not available. Therefore, we compared the results obtained by staining with 1, 5, 10, and 20μg/ml 7-AAD for 20min with the PE-Annexin V Apoptosis Detection Kit and Cell Death Detection ELISA(PLUS) in lymphocytes and CEM human leukemia cells. The results showed that 7-AAD staining with 5, 10, and 20μg/ml, but not with 1μg/ml, is suitable for quantification of apoptosis in flow cytometry.
