Resazurin (sodium salt)

Resazurin is a blue non-fluorescent dye that when reduced to the highly red-fluorescent product resorufin (ex/em max = 570/580 nm, respectively) can be used as a quantifiable detection agent for enzyme activity assays. The non-fluorescent resazurin can be used as an oxidation-reduction indicator in cell viability assays in a variety of cells.Formal Name: 7-hydroxy-3H-phenoxazin-3-one-10-oxide, monosodium salt.
