Product Description

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. Near-IR CF® Dye Annexin V does not contain azide or other potentially toxic materials, and thus is suitable for in vivo imaging.

  • Detect apoptotic cells with fast, reliable detection of phosphatidylserine externalization
  • No azide or other potentially toxic materials or preservatives, suitable for for in vivo imaging
  • Choice of 7 near-IR fluorescent CF® Dye colors
  • Biotium’s CF® Dyes are far more photostable and brighter than other similar near-IR dyes
  • Can be used for fluorescence microscopy, live cell imaging, and flow cytometry

Superior CF® Dyes

CF® Dyes are far more photostable and brighter than other similar near-IR dyes, such as Alexa Fluor® 700,  Alexa Fluor® 750, Cy®7 and IRDye® 800. Learn more about Near-IR CF® Dyes in the Near-IR Dye Flyer. Learn more about CF® Dyes.

Detect Apoptosis with Annexin V

We also offer Annexin V Conjugates, Azide-Free, and Lyophilized in colors ranging from UV to far-red for live cell staining. Annexin V Conjugate solutions (with azide) also are available with a large selection of CF® Dyes, biotin, R-PE, APC, and other labels. Annexin V is also available with other probes in our Apoptotic and Necrotic Staining Kits. See our full selection of Cell Viability and Apoptosis Assays.
