in order to characterize the cytochrome p-450 dependent aryl hydrocarbon hydroxylase activity in brain subcellular fractions , we used 7-ethoxyresorufin as a substrate , as its o-deethylation reflects specifically the activity of the cytochrome p-450 isoform which metabolizes and is induced by polycyclic aromatic hydrocarbons .
