Abstract
This invention provides a method for the determination of bicarbonate ion existing in liquid using phosphenolpyruvate carboxylase and malate dehydrogenase as conjugate enzyme wherein thioNAD(P)H is used as substrate of malate dehydrogenase. The use of the thioNAD(P)H enables the measurement with visible light, and enables the simple and accurate determination of bicarbonate ion concentration of biological liquid sample in the clinical test.
