Abstract
A method for assay of enzyme activity which comprises treating an amide compound of the formula ##STR1## with peptidase; treating thus-liberated amine of the formula ##STR2## with an oxidase which consume oxygen and forms pigment by oxidative condensation of said amine with a coupler of the formula ##STR3## and quantitatively measuring the detectable changes. Also disclosed is an assay method which comprises treating an amide compound of the formula ##STR4## or a salt thereof, with peptidase to liberate an aniline derivative of the formula ##STR5## oxidizing said aniline derivative; and quantitatively measuring detectable change.
