Annexin V-iFluor™ 488 conjugate

The detection of binding activity of Annexin V-iFluor™ 488 and phosphatidylserine in Jurkat cells. Jurkat cells were treated without (Blue) or with 20 µM camptothecin (Red) in a 37 °C, 5% CO2 incubator for 4-5 hours, and then dye loaded with Annexin V-iFluor™ 488 for 30 minutes. The fluorescence intensity of Annexin V-iFluor™ 488 was measured with a FACSCalibur (Becton Dickinson) flow cytometer using the FL1 channel.

Photostability of Annexin V-iFluor™ 488 (Red) and Annexin V-FITC (Blue). Jurkat cells were treated with 1 µM  staurosporine in a 37 °C, 5% CO2 incubator for 4-5 hours and then stained with Annexin V conjugate for 30min. The cells were continuously exposed to microscope (Keyence BZ-X710) excitation light source with a FITC filter for 5 min. Images were captured every second for 5 minutes, and total fluorescence intensity was normalized to the intenisty at 0 s.

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 Annexin V conjugate has spectral properties similar to Alexa Fluor® 488 (Alexa Fluor® 488 is the trademark of Invitrogen) and FITC.
