NAD+ 1000 MG

$105.00

NAD+ 1000 MG is a research-grade preparation of nicotinamide adenine dinucleotide, a fundamental redox coenzyme present in all living cells. NAD+ cycles between its oxidized (NAD+) and reduced (NADH) forms to shuttle electrons through central metabolic pathways including glycolysis, the citric acid cycle, and oxidative phosphorylation. Beyond its electron-carrier role, NAD+ is a required substrate for enzymes such as sirtuins and PARPs, linking it directly to research on cellular signaling and metabolic regulation. In laboratory studies, NAD+ is examined as a substrate and cofactor in cellular-bioenergetics research, where investigators measure redox ratios, mitochondrial function, and metabolic flux in cultured cells. It is also a key reference compound in sirtuin-pathway and PARP-activity assays, supporting in-vitro work on enzyme kinetics, deacetylation activity, and NAD+/NADH balance. Additional analytical use covers assay standardization and compound stability. Peptiva Research Labs supplies it as a research-grade reference compound, HPLC-verified with a COA available. For Research Use Only, not for human or veterinary use.

Frequently asked questions

What is NAD+?
NAD+ (nicotinamide adenine dinucleotide) is a redox coenzyme that carries electrons through central metabolic pathways and serves as a substrate for sirtuin and PARP enzymes. It is foundational to cellular energy metabolism. This preparation is intended solely for laboratory research.
What do researchers study NAD+ for?
It is used in vitro to measure redox ratios, mitochondrial function, and metabolic flux, and as a substrate in sirtuin and PARP enzyme assays. These studies examine enzyme kinetics and NAD+/NADH balance in cultured systems. All use is mechanistic and laboratory-confined.
How is NAD+ stored and reconstituted?
Store the sealed vial cold and protected from light, as NAD+ is sensitive to moisture and degradation. For in-vitro work it is typically dissolved in a suitable aqueous diluent immediately before use, with aliquots kept frozen. Refer to the COA for purity specifications.
