Immunofluorescence of NADPH-Cytochrome c (P450) Reductase in Rat and Minipig Tissues Injected with Phenobarbital

Abstract
The enzyme NADPH-cytochrome c (P-450) reductase was identified by indirect immunofluorescence in hepatocytes, bronchioles, and proximal tubules of liver, lung, and kidney, respectively, of rats and minipigs that had been injected with phenobarbital or saline. The distribution of this component of the cytochrome P-450-mediated microsomal system may be relevant to sites of drug toxicity and carcinogenesis.
