CEC [3-Cyano-7-ethoxycoumarin] *CAS 117620-77-6*

CEC

3-Cyano-7-ethoxycoumarin; CAS 117620-77-6

This fluorogenic coumarin ether is widely used for monitoring P450 activities in cell extracts and solutions. Cytochrome P450 oxidase (CYP450) is a large number of evolutionary related oxidative enzymes important in animal, plant, and bacterial physiology. Most cytochromes P450 (CYPs) have about 500 amino acids and a heme group at the active site.
