This flow cytometry product detects apoptosis on the basis of changes that occur in the permeability of cell membranes using PO-PRO™-1 and 7-aminoactinomycin D (7-AAD) nucleic acid stains. After staining a cell population with PO-PRO™-1 dye and 7-AAD, apoptotic cells show violet fluorescence, dead cells show violet and red fluorescence, and live cells show little or no fluorescence. These populations can easily be distinguished by a flow cytometer that uses both a violet laser and the 488 nm line of an argon-ion laser for excitation. Each kit contains sufficient reagents for approximately 200 flow cytometry tests.
