Description and Uses

Resorufin sodium salt is an anionic tricyclic dye with fluorescence. It can be used as an oxidation-reduction indicator in cell viability assays for both aerobic and anaerobic respiration.

Resorufin has been used to determine the cytochrome P450 (CYP) 2A5 coumarin 7-hydroxylase (COH) activity changes over a broad range of lipopolysaccharide (LPS) doses. It has also been used as an internal standard for ethoxyresurufin-o-deethylase (EROD) analysis.
