NAD+
Nicotinamide adenine dinucleotide
β-Nicotinamide Adenine Dinucleotide
Research context
NAD⁺ functions as an electron carrier in redox reactions and as a consumed substrate for sirtuin deacylases, poly(ADP-ribose) polymerases, and CD38. Research applications include enzyme kinetics requiring defined cofactor concentration, and studies of NAD⁺ pool depletion and restoration in cultured systems.
Common assays: Enzymatic cycling assay · LC-MS/MS quantification · Sirtuin activity coupling

Common questions
Why does NAD⁺ purity matter particularly in enzyme work?
NAD⁺ degrades to nicotinamide and ADP-ribose, both biologically active — nicotinamide inhibits sirtuins. Degradation products confound results, which is why free nicotinamide is reported separately on the certificate.
How stable is lyophilised NAD⁺?
It is hygroscopic and light-sensitive. Storage at −20 °C under desiccation is standard, and lots are handled and shipped accordingly.
