| Verified Reactivity | Human, Mouse, Rat |
|---|---|
| Reported Reactivity | Other 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. |
| Concentration | Lot-specific (to obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.) |
| Storage & Handling | The antibody solution should be stored undiluted between 2°C and 8°C. Do not freeze. |
| Application | FC - Quality tested |
| 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. |
Unless otherwise stated, the minimum order amount is USD 1,000.
For orders below USD 1,000, an additional handling fee may apply, or we may arrange local delivery / local handover where available.
All quotations are subject to final confirmation, including product availability, lead time, batch information, shipping cost, and applicable export or handling requirements.

| Application Notes |
|---|
| Annexin V Staining Wash cells twice with cold BioLegend Cell Staining Buffer (Cat. No. 420201) and then resuspend cells in Annexin V Binding Buffer (Cat. No. 422201) at a concentration of 1x106 cells/mL. Transfer 100 µL of cell suspension in 5 mL test tube. Add 5 µL of fluorochrome conjugated Annexin V. Stain with a viability dye, such as PI (Cat. No. 421301), 7-AAD (Cat. Nos. 420403 & 420404), or Helix NP dyes (Cat. Nos. 425301, 425303, & 425305), if desired. Gently vortex the cells and incubate for 15 min at RT (25°C) in the dark. Add 400* µL of Annexin V Binding Buffer (Cat. No. 422201) to each tube. *For more concentrated samples, add a minimum of 200 µl of Annexin V Binding Buffer in this step. Analyze by flow cytometry. For a better experience detecting apoptosis, we now recommend Apotracker™. Cell staining with Apotracker™ is Calcium independent. Thus, no special buffers are required, and the protocol can be shortened for single-step co-staining with other reagents. |
