Detect Apoptosis with Annexin V

Annexin V is a 35-36 kDa protein that has a high affinity for phosphatidylserine (PS). In normal viable cells, PS is located on the cytoplasmic surface of the cell membrane. In apoptotic cells, however, PS is translocated from the inner to the outer leaflet of the plasmic membrane, making itself available for Annexin V binding.

Biotium offers Annexin V conjugated to a wide range of CF® Dyes and other fluorescent dyes, including our unique range of near-infrared CF® Dyes. We also provide azide-free Annexin V conjugates for live cell staining.
