What is annexin V Binding Buffer?

What is annexin V Binding Buffer?

The Annexin V Binding Buffer is a 10X concentrate composed of a 0.2 µm sterile filtered 0.1M Hepes (pH 7.4), 1.4M NaCl, and 25 mM CaCl2 solution. Prior to staining cells, an appropriate quantity of a 1X working solution should be made by diluting the 10X concentrate 1:10 with distilled water.

What is fitc annexin V?

Product overview. Annexin V-FITC Apoptosis Staining / Detection Kit ab14085 is used in a 10 min, one-step staining procedure to detect apoptosis by staining phosphatidylserine molecules which have translocated to the outside of the cell membrane. Analysis is by flow cytometry or fluorescence microscopy.

How does Annexin V detect apoptosis?

Why is annexin V staining used to detect apoptosis? Fluorescent conjugates of annexin V are commonly used to identify apoptotic cells. It has been reported that the translocated phosphatidylserine on the outer surface of the cell marks the cell for recognition and phagocytosis by macrophages (1).

How do you use BioLegend biotin annexin V binding buffer?

1. 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 1×10 6 cells/ml. 2. Transfer 100 µl of cell suspension in 5 ml test tube. 3. Add 5 µl of Biotin Annexin V.

What is the best binding buffer for annexin V reagents?

Annexin V Binding Buffer is recommended for use with Annexin V reagents. Cells should be resuspended in Annexin V Binding Buffer at a concentration 1×10 6 /ml and then combined with Annexin V reagents at the recommended volumes.

How do you add annexin V to cell suspension?

Add 5 μL of fluorochrome-conjugated Annexin V to 100 μL of the cell suspension. Incubate 10-15 minutes at room temperature. Protect from light. Add 2 mL 1X binding buffer and centrifuge at 400-600 x g for 5 minutes at room temperature. Discard supernatant. Resuspend cells in 200 µL of 1X binding buffer.

How do you use annexin V to identify apoptotic cells?

Fluorochrome-labeled Annexin V can then be used to specifically target and identify apoptotic cells. Annexin V Binding Buffer (cat. no. 422201) is recommended for use with Annexin V staining.Annexin V binding alone cannot differentiate between apoptotic cells and necrotic.
