PURPOSE: To shorten the time necessary for the determination of enzymatic activity with a dry analytic element containing a water-permeable liquid- developing layer and a reagent, by including a substrate, an oxidized coenzyme and an electron-transfer agent in the former layer and a pigment precursor in the latter layer.
CONSTITUTION: The objective dry analytic element is composed of a water- permeable reagent layer placed opposite to the liquid-receiving surface of a liquid-developing layer. The developing layer contains the major parts of 3 components comprising a substrate, an oxidized coenzyme and an electron- transfer agent and the reagent layer contains the major part of a pigment precursor. Preferably, the developing layer contains a substrate for a lactate dehydrogenase.
