Description: | Andy Fluor™ 680 Annexin V is Annexin V conjugated with our far-red fluorescent dye Andy Fluor™ 680. Annexin V is a calcium-dependent phospholipid-binding proteins, which bind to phosphatidylserine (PS) to identify apoptotic cells. 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 plasma membrane, making itself available for Annexin V binding. Andy Fluor™ 680 is a superior alternative to Cy5.5, or Alexa Fluor® 680 owing to its exceptional brightness and photostability. |
