Procedure
Harvest cells and aliquot up to 1 x 106 cells/100 μL into FACS tubes. Wash the cells by adding 2 mL PBS (or HBSS), centrifuging at 300 x g for 5 minutes and then decanting the buffer from pelleted cells. Repeat wash step for a total of 2 times.
Note: Staining of cell surface antigens with antibodies may be done at this point. 7-AAD cannot be used when labeling intracellular molecules.
Resuspend cells in 100 μL of Flow Cytometry Staining Buffer (Catalog # FC001).
To adjust flow cytometer settings for 7-AAD, add 5 - 10 μL of 7-AAD staining solution to a control tube of unstained cells. Mix gently and incubate for 30 minutes at 4 °C in the dark.
Determine 7-AAD fluorescence (using the FL-2 or FL-3 channel) with a FACScan™ instrument.
Note: Use the FL-2 channel if staining only with 7-AAD. Collect 7-AAD fluorescence in the FL-3 channel if the cells have also been stained with an FITC- and/or PE-conjugated antibody.
Acquire data for unstained cells and single-color positive controls.
Add 5 - 10 μL of 7-AAD staining solution to each sample and incubate for 30 minutes at 4 °C in the dark prior to analysis. Set the stop count on the viable cells from a dot-plot of forward scatter versus 7-AAD.
Note: Do not wash cells after the addition of the 7-AAD staining solution.
