What is Methoxyresorufin?
Description
Methoxyresorufin is a fluorogenic substrate for the cytochrome P450 (CYP) isoforms CYP1A1 and CYP1A2. Methyoxyresorufin is O-demethylated by CYP1A1/2, releasing resorufin, which displays excitation/emission maxima of 570/580 nm, respectively. The appearance of resorufin fluorescence can be used to quantify CYP1A1/2 activity.
The Uses of Methoxyresorufin
Substrate for Cytochrome P-450. METHOXYRESORUFIN is used for various investigations including the differentiatiation of cytochrome P-450 isozymes.
The Uses of Methoxyresorufin
Resorufin methyl ether have been used as substrate in the incubation mixture, during the determination of cytochrome P4501A activities such as ethoxyresorufin O-deethylase (EROD) and methoxyresorufin O-demethylase(MROD) in liver microsomes, using high performance liquid chromatography(HPLC).
The Uses of Methoxyresorufin
Used to differentiate isozymes of cytochrome P-450
