Abstract
Nicotinamide adenine dinucleotide (NAD+) and its related metabolites (NADome) are important endogenous analytes that are thought to play important roles in cellular metabolism, inflammation, oxidative stress, cancer, neurodegeneration, and aging in mammals. However, these analytes are unstable during the collection of biological fluids, which is a major limiting factor for their quantitation. Herein, we describe a highly robust and quantitative method using liquid chromatography coupled to tandem mass spectrometry to quantify the NADome in whole blood, plasma, mononuclear cells, platelets, cerebrospinal fluid (CSF), and urine. This methodology represents a “gold standard” of measure for understanding biological pathways and developing targeted pharmacological interventions to modulate NAD+ biosynthesis and NAD-dependent mediators in health and disease.
