Many cellular metabolites can be measured with high sensitivity using bioluminescent techniques. These metabolites are coupled to an appropriate enzyme to produce NAD(P)H, which can then be coupled to the bioluminescent reactions. The sensitivity of bioluminescence cannot be readily applied to methods in which cellular metabolites consume NAD(P)H because of the difficulty in measuring, with sufficient sensitivity, decreases in the concentration of NAD(P)H against a high background NAD(P)H concentration. We have overcome these technical difficulties by developing a bioluminescent reagent to measure the production of NAD(P)(+). Assays for creatine/creatine phosphate, pyruvate, and succinate, as well as the kinetic measurement of lactate, are described for a range of biological material. The assays are highly sensitive, quantitative, and reproducible and show no sample-specific inhibition. The range of assays and the diverse biological material tested suggests that NAD(P)(+) bioluminescence has a wide potential for application. (C) 1999 Academic Press.
