Abstract
Phenobarbital-inducible cytochrome P450 variants have a higher affinity (app. Ks = 0.6 microM). The difference in affinity has enabled us to quantitate, by metyrapone-induced difference spectral analysis, phenobarbital-inducible cytochromes P450 in liver microsomal membranes. The result obtained by this simple, rapid technique compare well with those found by more sophisticated techniques such as radioimmunoassay and immunoprecipitation.
