XTT (sodium salt hydrate)

XTT is a cell-impermeable, negatively charged tetrazolium dye that produces a water-soluble formazan when reduced at the cell surface by cellular-derived NADH and an electron mediator. It is frequently used in colorimetric assays to measure cell proliferation, cytotoxicity, and apoptosis.Formal Name: 2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino)carbonyl]-2H-tetrazolium, inner salt, monosodium salt, hydrate.
