Protocol:General Protocol - Detection of apoptotic cells by flow cytometry
- Harvest 2x105 cells per staining and wash cells twice in cold phosphate- buffered-saline (PBS).
- Resuspend cells in 100µl binding buffer (10mM HEPES, pH 7.4, 140mM sodium chloride, 2.5mM calcium dichloride), add 5µl annexin V-Alexa Fluor® 488 to the cells and mix gently.
For detection of necrosis add additionally appropriate amounts of propidium iodide (final concentration 1µg/ml or 1.5µM).
- Incubate for 15 min. at room temperature in the dark.
- Add 400µl binding buffer and analyze the staining in flow cytometry as soon as possible (within an hour).
Figures: Immature mouse B-cells were treated with Fab2-antibodies for 24 hours. Stimulated ((B), after anti-IgM cross-linking) and unstimulated premature mouse B-cells ((A) WEHI231) were stained with Annexin-AlexaFluor® 488 as described [1] and analyzed in flow cytometry.
