Background / Technical Information:Flow Cytometry Protocol:
- Prepare binding buffer (10mM Hepes/NaOH, pH 7.4, 140mM NaCl,  2.5mM CaCl2; filtered through  0.2µm pore filter).
- Brief centrifugation of annexin V-FITC before use is recommended
- Wash cells in PBS by gentle shaking or pipetting up and down.
- Resuspend cells in binding buffer; adjust cell density to 2-5x105/ml
- Take 195µl cell suspension and add 5µl annexin V-FITC
- Mix and incubate 10 min. in the dark at room temperature
- Wash cells 1x with PBS and resuspend in 190µl binding buffer
- Add 10µl of 20µg/ml propidium iodide stock solution (end concentration 1µg/ml)- FACS analysis
