A sensitive radioisotopic method for the measurement of NAD(P)H: its application to the assay of metabolites and enzymatic activities.

A Sener1, W J Malaisse.   

Abstract

A radioisotopic method for the assay of NADH or NADPH is presented, which is based on the conversion of 2-[U-14C]ketoglutarate to 14C-labeled glutamate in the reaction catalyzed by glutamate dehydrogenase. The efficiency of the method is close to 75%, its precision (coefficient of variation) close to 5%, and its sensitivity close to 0.1 pmol/sample. This simple and rapid method can be applied to the measurement of several metabolites and enzymatic activities. In the present study, its application to the assay of sorbitol, 3-hydroxybutyrate, glutamate dehydrogenase, 3-hydroxybutyrate dehydrogenase, and glyceraldehyde-3-phosphate dehydrogenase is documented.
