NAD+ — a central metabolic coenzyme used as a research-grade reference compound for metabolism, sirtuin, and DNA-repair studies.

NAD+ (the oxidized form of nicotinamide adenine dinucleotide) is one of the most important molecules inside every cell. It shuttles electrons during energy production and is the fuel for sirtuin enzymes (involved in cell-aging research), PARP enzymes (DNA repair), and CD38 (immune signaling). In the lab, it's a standard reference compound.
How it's been studied: Researchers use NAD+ in two main ways: as the substrate in enzyme-activity assays (especially sirtuin and PARP assays), and as a reference for measuring the cellular NAD+/NADH ratio — a popular readout of metabolic health in cultured cells.
