ABSTRACT:
An analysis film for assaying transaminase activity comprises a reagent layer containing pyruvic acid oxidase, a combination of a hydrogen donor and a coupler--which is capable of forming a cationic dye--and an anionic polymer. The cationic dye formed by the reaction with a color indicator composition for detecting hydrogen peroxide is fixed with the anionic polymer, thereby mobilization and diffusion of the cationic dye being prevented so that the analysis film achieves high detection sensitivity and high accuracy.
