7AAD STAINING OF NONVIABLE CELLS
- Add 1µl of 1 mg/ml 7-AAD (1µg/ml final) to approximately 1x106 washed cells suspended in 1ml PBS.
- Incubate ≥ 30 minutes in the dark on ice.
- Analyze on flow cytometer with excitation at 488nm. Collect fluorescence emission with a 650nm long-pass or a 670±20nm band-pass filter.
7-AAD is easily excitable at 488nm. The fluorescence emission of the dye has a peak at ~670nm.
