Nicotinamide adenine dinucleotide (NAD+) is an endogenous dinucleotide coenzyme found in all living cells, functioning as an essential electron carrier in redox metabolism and as a co-substrate for regulatory enzyme classes including sirtuins, PARPs, and CD38. Its molecular weight is approximately 663 Da (free acid). This 100mg vial provides a research-scale quantity of NAD+ for laboratory applications such as enzyme activity assays, cell-based studies, and pilot in vitro experiments.

### Research Background

Published laboratory research has examined NAD+ in the context of mitochondrial bioenergetics, cellular aging models, and DNA damage response. Investigators have studied NAD+ flux through the biosynthesis and salvage pathways using isotopic tracing in cell culture systems. Research has explored intracellular NAD+/NADH ratios as indicators of metabolic state in models of caloric restriction, hypoxia, and genotoxic stress. Published studies have examined NAD+ as a limiting substrate for sirtuin-1 (SIRT1) deacetylase activity in gene regulation models. In vitro and cell-based research has also examined the downstream effects of modulating NAD+ availability on mitochondrial biogenesis markers and senescence-associated secretory phenotype (SASP) components.
