NAD+
NAD+ (Nicotinamide adenine dinucleotide)
Also known as Nicotinamide adenine dinucleotide
NAD+ is a dinucleotide coenzyme present in all living cells, functioning both as an electron carrier in redox reactions and as a consumed substrate for sirtuins, PARPs, and CD38. It is not a peptide. Research interest in the longevity context follows from the observation that tissue NAD+ concentration declines with age, and from the dependence of sirtuin activity on NAD+ availability.
Research applications
- Sirtuin activity and deacetylation assays
- PARP-mediated DNA repair studies
- Mitochondrial respiration and redox state measurement
- CD38 and NAD+ consumption pathway research
Storage
Store lyophilized at -20°C protected from light and moisture. NAD+ is hygroscopic and degrades in solution faster than most peptides — prepare fresh where the assay permits.
Reconstitution
Reconstitute with bacteriostatic or sterile water. Solutions are less stable than peptide solutions; use promptly.
