Vybrant® Apoptosis Assay Kit #6, Biotin-X Annexin V/Alexa Fluor® 350 Streptavidin/Propidium Iodide

Description

The Vybrant Apoptosis Assay Kit #6 uses the bright, blue-fluorescent Alexa Fluor 350 conjugate of streptavidin in conjunction with biotin-X annexin V to detect apoptotic cell populations either by flow cytometry or imaging. Alexa Fluor 350 streptavidin binds to biotin-X annexin V, which in turn binds to the phosphatidylserine on the surfaces of apoptotic cells. Necrotic cells are distinguished using red-fluorescent propidium iodide, which binds tightly to the nucleic acids in those cells. Propidium iodide does not penetrate the plasma membranes of live cells or early apoptotic cells. The kit contains an ample amount of each reagent for about 50 flow cytometric assays.
