Jurkat cells were cultured with (Left) or without (Right) 5 µM Camptothecin for 4 h. Annexin V-FITC single-positive cells were early apoptotic cells, Annexin V-FITC and PI double-positive cells were necrotic or late apoptotic cells, and PI single-positive cells were naked nuclei.

Datasheet SDS
Annexin V is used as a probe to detect cells that have expressed phosphatidylserine (PS) on the cell surface, an event found in apoptosis as well as other forms of cell death. The Annexin V affinity assay typically uses a conjugate of annexin V and a fluorescent or enzymatic label, biotin or other tags, or a radioelement, in a suitable buffer (Annexin V binding to PS is Ca2+ dependent). The assay combines Annexin V staining of PS membrane events with the staining of the cell nucleus with PI or AAD-7 to distinguish living cells from dead cells. Annexin V apoptosis detection is based on the observation that soon after initiating apoptosis, cells translocate the membrane phosphatidylserine (PS) from the inner (cytoplasmic-facing) leaflet of the plasma membrane to the cell surface. Once on the cell surface, PS can be easily detected by staining with a fluorescent conjugate of Annexin V, a protein that has a high affinity for PS. Detection can be analyzed by flow cytometry or by fluorescence microscopy.

This product contains Annexin V (FITC) only and does not include 10X Binding Buffer, PI or 7-AAD reagents.

Directions for use Suggested Staining Procedure:
  1. Induce apoptosis of suspension cells with reagents of interest. Collect cell cultures, centrifuge at 300 × g for 5 min and discard the supernatant. Add PBS to wash the cells and resuspend the cells gently. Carry out cell counting.
  2. Split the cell suspension into tubes, each containing 1-5 × 105 cells. Centrifuge at 300 × g for 5 min and discard the supernatant. Add PBS to wash the cells, then discard the supernatant. Add 500 µl of 1X Annexin V Binding Buffer (abx090621) to resuspend the cells.
  3. Add 5 µl of Annexin V-FITC Reagent and 5 µl of DNA dye (PI, 7-AAD or DAPI) to each tube.
  4. Gently vortex the cells and incubate at room temperature for 15-20 min in the dark.
  5. Analyze the cells immediately with appropriate machine settings, or place the cells on ice in the dark and analyze within 1 h.
Notes:
  • When detecting adherent cells, the suspension cells generated after induction of apoptosis should be collected and detected together with the subsequently collected adherent cells.
  • Mechanical damage caused by digestion of adherent cells should be avoided. The trypsin digestion solution should not contain EDTA, because EDTA will affect the binding of Annexin V to phosphatidylserine. If trypsin-containing EDTA is used, cells should be washed thoroughly after harvesting to ensure that EDTA is removed.
  • Analyze as soon as possible after staining. Avoid extended exposure of the samples to direct light to protect the fluorophores from quenching.
  • Wear appropriate personal protective equipment (PPE), such as lab coats, safety glasses, and disposable gloves, when carrying out the assay.
