QUICK LINKS

Resorufin methyl ether is a fluorometric substrate for cytochrome P450 linked enzymes. Resorufin methyl ether is a substrate of CYP. This widely utilized fluorogenic resorufin ether is employed to monitor the activities of P450 in both cell extracts and solutions. Cytochrome P450 oxidase (CYP450) refers to a multitude of evolutionarily linked oxidative enzymes that hold significance in the physiology of animals, plants, and bacteria. The majority of cytochromes P450 (CYPs) consist of approximately 500 amino acids and feature a heme group situated at the active site.
