1 A monoclonal antibody (MAb 1-7-1), which recognizes isozymes of cytochrome P-450 induced by 3-methylcholanthrene (P1-450 and P3-450), selectively inhibited the metabolism of 8-MOP (-57%) and covalent binding of its metabolites (-40%) in microsomes from mice pretreated with BNF, but had no effect in microsomes of mice pretreated with phenobarbital or vehicle. Phenobarbital cytochrome P450, family 21, subfamily a, polypeptide 1 Mus musculus
