title: Noninducibility of cytochrome P-450 in the earthworm Dendrobaena veneta.
abstract: Cytochrome P-450 has been measured in the earthworm Dendrobaena veneta (Rosa) in a direct spectrophotometric procedure. The P-450 was found not in the dense microsomal fraction, but in the less dense overlying fraction often referred to as buffy coat. Earthworm P-450 was not induced by 3-methylcholanthrene or phenobarbitol.
