Description and Uses

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.

Resazurin Sodium Salt is used as an indicator in fluorescence assays.
