subcellular fractionation showed the enzyme associated with the post-mitochondrial supernatant fraction in each of the tissues : specific activities of odc , defined as alpha-difluoromethylornithine ( dfmo ) -sensitive decarboxylation of ornithine , in the supernatant fractions of combined inner ear tissues were : guinea pig = 44 +/- 4 pmoles co2 produced/hour/mg protein , and rat = 133 +/- 30 .
