Annexins are a family of proteins that bind to phospholipid membranes in the presence of calcium. Annexin V is a valuable tool for studying cell apoptosis. It is used as a probe to detect cells which have expressed phosphatidylserine on the cell surface, a feature found in apoptosis as well as other forms of cell death. There are a variety of parameters that can be used for monitoring cell viability. Annexin V-dye conjugates are widely used to monitor cell apoptosis through measuring the translocation of phosphatidylserine (PS). In apoptosis, PS is transferred to the outer leaflet of the plasma membrane. The appearance of phosphatidylserine on the cell surface is a universal indicator of the initial/intermediate stages of cell apoptosis and can be detected before morphological changes can be observed. This fluorescent FITC-Annexin V conjugate is widely used for monitoring cell apoptosis with a flow cytometer or a fluorescence microscope. For microplate assays of annexin V-based cell apoptosis detection, we recommend you use our Cell Meter™ kits.

Figure 1. The detection of binding activity of FITC-Annexin V conjugate to phosphatidylserine in Jurkat cells. Jurkat cells were treated without (Green) or with 1 μM staurosporine (Red) in 37 ºC for 4 hours, and then labeled with FITC-Annexin V conjugate for 30 minutes. Fluorescence intensity was measured using ACEA NovoCyte flow cytometer in FITC channel.
