A method of assaying enzymes such as protease, comprising the step (1) of bringing an enzyme-containing specimen into contact with a thin film containing both of an organic compound having a visible ray absorption that varies by the reaction with an enzyme and a hydrophilic macromolecule such as gelatine and the step (2) of detecting discernible traces formed on the film by the action of the enzyme.
L'invention se rapporte à une méthode d'analyse d'enzymes tels que des protéases. Cette méthode consiste (1) à amener un échantillon contenant des enzymes en contact avec un film fin contenant à la fois un composé organique dont l'absorption du rayonnement visible est modifiée par réaction avec un enzyme, et une macromolécule hydrophile telle que la gélatine, et (2) à déceler les traces susceptibles d'être discernées formées sur le film par l'action de l'enzyme.
