Description
NAD+ (CAS: 53-84-9) (Nicotinamide Adenine Dinucleotide, beta-NAD) is an endogenous dinucleotide coenzyme found in all living cells, supplied by AusPepLabs for laboratory and analytical research applications. First discovered in 1906 by Harden and Young during investigations into yeast fermentation, NAD+ has since become one of the most extensively studied coenzymes in cellular biology. Each vial is independently verified to ≥99% HPLC purity with a Certificate of Analysis available on request. For scientific research use only.
Why Research Laboratories Select NAD+
NAD+ is one of the most fundamental and extensively studied coenzymes in biological research. As a central mediator of redox reactions – alternating between its oxidized (NAD+) and reduced (NADH) forms – it participates in over 500 enzymatic reactions and serves as an essential reference compound for laboratories investigating cellular energy metabolism, sirtuin biology, DNA repair pathways, and redox signaling.
- Essential dinucleotide coenzyme – mediates electron transfer in cellular metabolic pathways
- Substrate for sirtuin enzymes (SIRT1-7) studied in the context of gene regulation and cellular stress response
- Substrate for PARP enzymes studied in DNA repair pathway research
- Studied as an extracellular signaling molecule in neuronal and vascular biology research models
- Central to glycolysis, citric acid cycle, and electron transport chain research models
- Referenced in hundreds of peer-reviewed publications across cellular and molecular biology
