title: Multiple forms of cytochrome P-450 from microsomes of rat liver, kidney, and lung resolved by high-performance liquid chromatography.
abstract: The amount of cytochrome P-450 in microsomes of rat kidney and lungs was 23 and 7%, respectively, of the amount in microsomes of the liver. HPLC profiles of solubilized microsomes showed that there were five or more forms of cytochrome P-450 in microsomes of kidneys and also of lungs of untreated rats. While 3-methylcholanthrene induced a new form of cytochrome P-450 in kidney and lung microsomes, phenobarbital caused no major change in the HPLC profiles of these microsomes.
