Abstract
Pyridine nucleotides which include NAD+, NADH, NADP, and NADPH play vital roles in many different biological processes. These metabolites can be accurately quantified in a wide variety of biological samples using LC-MS/MS. The quality and precision of these measurements was enhanced using heavy isotope-labeled internal standards and carefully crafted protocols for sample processing.
