METHOD FOR ASSAY OF INTESTINAL DISACCHARIDASES.

Abstract 1. 1. A procedure is described for assay of disaccharidase activities in extracts of intestinal mucosa, using a Tris-glucose oxidase reagent for assay of the glucose liberated from the substrate. The incubation conditions are discussed. 2. 2. A unit for disaccharidase activity is defined that is in accord with recommendations made by the Joint Sub-Commission on Clinical Enzyme Units of the International Unions of Biochemistry and of Pure and Applied Chemistry.
