Product Details
NAD+ (Nicotinamide Adenine Dinucleotide, Oxidized Form) — Research Grade, ≥98% Purity (HPLC) NAD Peptide
Redox coenzyme. Electron carrier. Lyophilized powder. Lot-specific COA included.
NAD Peptide (β-nicotinamide adenine dinucleotide, oxidized form) is a dinucleotide coenzyme that functions as the primary electron carrier in cellular redox reactions. Together with its reduced form, NADH, it constitutes the NAD+/NADH redox pair central to oxidative phosphorylation, glycolysis, and a wide range of enzyme-catalyzed oxidation-reduction reactions. It also serves as a substrate for NAD+-consuming enzymes including sirtuins, PARPs, and CD38. NAD Peptide
The coenzyme is not a peptide. It is composed of two nucleotides — adenine and nicotinamide — linked by a pyrophosphate bond. It is supplied as a lyophilized powder for in vitro and preclinical research applications. Each lot is independently verified for purity and identity and ships with a Certificate of Analysis.

Research applications
NAD+ is used in laboratory settings to investigate:
-
Cellular redox metabolism — electron transfer in oxidative phosphorylation and glycolysis in mitochondrial and cell culture models
-
Sirtuin and PARP pathway research — NAD+ availability as a substrate for sirtuins and poly(ADP-ribose) polymerases in cellular senescence and DNA repair studies
-
Cellular senescence and aging research — replenishment of intracellular NAD+ levels and inhibition of senescence in periodontal ligament stem cells, with polyphenol-NAD+ nanoparticles effectively replenishing NAD+ and scavenging ROS
-
Oocyte maturation research — NAD+ generated from nicotinamide mononucleotide (NMN) and its role in F-actin polymerization, spindle assembly, and oocyte quality in post-ovulatory aged porcine oocytes
-
Acute brain injury and neuroprotection — NAD+ delivery to energy-depleted cells, with reports suggesting NAD+ can decrease neuronal death from oxygen-glucose deprivation and prevent mitochondrial depolarization
-
Enzymatic assay development — NAD+/NADH quantification and dehydrogenase-coupled reaction systems for analytical method development
Handling and storage
Reconstitute under aseptic conditions using sterile water or an appropriate aqueous buffer. NAD+ is soluble in water. Aliquot immediately after reconstitution to avoid repeated freeze-thaw cycles. Lyophilized powder is stable for up to 3 years at −20 °C or 2 years at 4 °C; reconstituted solutions are stable for 1 year at −80 °C or 6 months at −20 °C. nad peptide
