This product detects the externalization of phosphatidylserine in apoptotic cells using recombinant annexin V conjugated to violet-fluorescent Pacific Blue™ dye and dead cells using SYTOX™ AADvanced™ stain. After staining a cell population with Pacific Blue™, annexin V and SYTOX™ AADvanced™, apoptotic cells show violet fluorescence, dead cells show red fluorescence, and live cells show little or no fluorescence. These populations are easily distinguished by a flow cytometer with the 405 nm and 488 nm lines for excitation. There is very little spectral overlap between the two dyes, therefore very little compensation is needed. Each kit contains sufficient reagents for approximately 50 flow cytometry tests.
I want to study apoptosis using an Annexin V conjugate, but with adherent cells via microscopy instead of flow cytometry. Can this be done?
It has been done, but we dont recommend it. Both healthy cells and apoptotic cells possess phosphatidylserine on the cell surface, which can be detected with Annexin V, but apoptotic cells have significantly more of it. You can easily tell the difference between these two populations with flow cytometry, because flow cytometers are more sensitive and have a higher throughput. But with a microscope, you cannot always tell the difference, especially for adherent cells. Instead, for microscopy, we recommend a different technique, such as detecting caspases with CellEvent Caspase Detection Reagents.
