title: Enzymatic and non-enzymatic assay of superoxide dismutase.
abstract: Superoxide dismutase from breef brain and rat liver was assayed in an enzymatic system, using xanthine oxidase, and a non-enzymatic system, based on aerobic reduction of nitro-blue tetrazolium in presence of phenazine methosulphate. The non-enzymatic assay is rapid and simple and permits simulatneous analysis of many samples.  Similar results are  found by the two methods of assay of superoxide dismutase.
