摘要：

An easy purification of rat liver microsomal cytochrome P448 was performed by using 3,4,5,3′,4′-pentachlorobiphenyl as an inducer. The cytochrome P448, a high spin form, was purified to 18.1 nmoles/mg protein with a good yield by ω-aminooctyl Sepharose 4B column chromatography followed by a hydroxyapatite column chromatography. This hemoprotein cross-reacted with antibody to cytochrome P448 from β-naphthoflavone-treated rats, but not with antibody to cytochrome P450 from phenobarbital-treated rats at all. The results of amino acid analyses suggested that this cytochrome P448 is similar to cytochrome P448 of 3-methylcholanthrene-treated rats. © 1979.
