Reactivity: All mammalian species
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and 0.2% (w/v) BSA (origin USA).
Preparation: The purified protein was conjugated with biotin under optimal conditions. The solution is free of unconjugated biotin and unconjugated antibody.
Concentration: Lot-specific (please contact technical support for concentration and total µg amount, or use our Lookup tool if you have a lot number.)
Storage & Handling: The Annexin V solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light. Do not freeze.
Application:

FC - Quality tested

Application Notes:

Annexin V Staining 
1.
2. Transfer 100 µl of cell suspension in 5 ml test tube.
3. Add 5 µl of Biotin Annexin V.
4. Add 10 µl of PI solution or 7-AAD . 
5. Gently vortex the cells, and incubate for 15 min at room temperature (25°C), in the dark. 
6. Add 400 µl of Annexin V Binding Buffer to each tube. Analyze by flow cytometry.

Recommended Usage:

Each lot of this product is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µl per 100,000 - million cells in a 100 µl volume of Annexin V Binding Buffer (Cat No. 422201). It is recommended that the reagent be titrated for optimal performance for each application.

Human T-cell leukemia cell line,

Human T-cell leukemia cell line, Jurkat, was treated with (filled histogram) or without (open histogram) LEAF™ purified anti-CD95 (clone EOS9.1) for 4 hours, then stained with biotinylated Annexin V, followed by Sav-PE.



Description:

Annexin V (or Annexin A5) is a member of the annexin family of intracellular proteins that binds to phosphatidylserine (PS) in a calcium-dependent manner. PS is normally only found on the intracellular leaflet of the plasma membrane in healthy cells, but during early apoptosis, membrane asymmetry is lost and PS translocates to the external leaflet. Fluorochrome-labeled Annexin V can then be used to specifically target and identify apoptotic cells. Annexin V Binding Buffer is recommended for use with Annexin V staining. Annexin V binding alone cannot differentiate between apoptotic cells and necrotic. So, we recommend using our 7-AAD Viability Staining Solution or Propidium Iodide Solution . Early apoptotic cells will exclude 7-AAD and PI, while late stage apoptotic cells and necrotic cells will stain positively, due to the passage of these dyes into the nucleus where they bind to DNA.
