title: [Comparative characteristics of isolated forms of cytochrome P-450 induced by phenobarbital and perfluorodecalin].
abstract: Two forms of cytochrome P-450 were isolated from liver microsomes of perfluorodecalin-induced rats and purified to homogeneity. A comparison of these forms with cytochromes P-450b and P-450e obtained from phenobarbital-induced rat liver microsomes revealed their similarity in a number of properties, e.g., chromatographic behaviour on 1.8-diaminooctyl-Sepharose 4B and DEAE-Sephacel columns, molecular mass determined by SDS polyacrylamide gel electrophoresis, spectral properties, immunoreactivity, peptide mapping, catalytic activity. These findings suggest that in rat liver microsomes perfluorodecalin and phenobarbital which differ in their chemical structure induce identical forms of cytochrome P-450.
