This flow cytometry product detects the externalization of phosphatidylserine in apoptotic cells using recombinant annexin V conjugated to red laser-excited allophycocyanin, and dead cells using SYTOX™ Green nucleic acid stain. Apoptotic cells are detected by annexin V binding to externalized phosphatidylserine, and late apoptotic and necrotic cells have compromised membranes that permit SYTOX™ Green stain access to cellular nucleic acids. After exposing a cell population to APC annexin V and SYTOX™ Green stain, live cells show little or no fluorescence, apoptotic cells show red fluorescence and very little green fluorescence, and late apoptotic cells show a higher level of red and orange fluorescence. These populations can easily be distinguished using a flow cytometer that has both 488 nm and 633 nm excitation sources (an argon-ion laser and a HeNe laser).
