title: Inhibition of microsomal NAD(P)H oxidation by Triton X-100.
abstract: The non-ionic detergent Triton X-100 is shown to inhibit the spontaneous oxidation of NAD(P)H associated with rat liver microsomes. Advantage of this observation is taken to measure different microsomal NAD(P)H-dependent oxidoreductase activities such as 3-alpha-hydroxysteroid dehydrogenase, dihydrodiol dehydrogenase and various xenobiotic oxidoreductases. This inhibition provides an easy method for the screening of the under-investigated microsomal oxidoreductive metabolism of xenobiotics.
