Product Description

Annexin V fluorescent conjugates can be used to detect apoptotic cells. The human anticoagulant Annexin V is a 35-36 kDa calcium-dependent phospholipid-binding protein with high affinity for phosphatidylserine (PS). In normal viable cells, PS is located on the inner leaflet of the cytoplasmic membrane. In apoptotic cells, however, PS is translocated from the inner to the outer leaflet of the plasma membrane, where it can be detected by fluorescently labeled Annexin V.

  • Detect apoptotic cells with fast, reliable detection of phosphatidylserine externalization
  • Conjugates with wide choice of CF® dye colors, plus biotin, R-PE, APC, and other fluorescent dyes
  • Biotium’s CF® dyes have superior brightness, photostability, and are water-soluble
  • Can be used for fluorescence microscopy, live cell imaging, and flow cytometry

CF® Dye, biotin, and FITC conjugates of Annexin V are provided as 50 ug/mL solutions in 10 mM Tris, 1 mM EDTA, 30 mM NaCl, 1 mg/mL bovine serum albumin, 0.1% sodium azide, pH 7.5. R-PE and APC Annexin V conjugates are supplied in PBS, 5 mg/mL BSA, 0.05% sodium azide at 5 uL per test.

Detect Apoptosis

We also offer Annexin V Conjugates, Azide-Free and Lyophilized in colors ranging from UV to far-red for live cell staining, and Near-IR CF® Dye Annexin V (also lyophilized and preservative-free), compatible with small animal NIR in vivo imaging. 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.

Superior CF® Dyes

Biotium’s next-generation CF® dyes were designed to be highly water-soluble with advantages in brightness and photostability compared to Alexa Fluor®, DyLight®, and other fluorescent dyes. Learn more about CF® Dyes.

Note: Conjugates of blue-fluorescent dyes like CF®350, CF®405S and CF®405M are not recommended for detecting low abundance targets and may be challenging to use in tissue specimens. Blue dyes have lower fluorescence and photostability, and cells and tissue have high autofluorescence in blue wavelengths, resulting in lower signal to noise compared to other colors.
