NAD⁺ is a naturally occurring coenzyme found in all living cells, central to cellular energy metabolism and redox biochemistry. Supplied as a lyophilized powder in a sealed laborat ory-grade glass vial. Intended for in-vitro and laboratory research applications only.Research ContextNAD⁺ acts as a hydride-transferring coenzyme in cellular redox reactions, cycling between its oxidized (NAD⁺) and reduced (NADH) forms within mitochondrial and cytoplasmic metabolic pathways including glycolysis, the citric acid cycle, and oxidative phosphorylation. It is also a substrate for sirtuin deacylases (SIRT1–7), poly(ADP-ribose) polymerases (PARPs), and CD38 signalling, making it a subject of in-vitro and animal-model studies into DNA-repair, mitochondrial-biogenesis, and inflammatory signalling pathways. Its documented decline with age makes it a research subject in the study of longevity biology, metabolic pathways, and neuronal signalling.Specifications• Sequence: Validated by mass spectrometry (MS/MS)• Purity: ≥ 99% by HPLC• Form: Lyophilized powder• Molecular Weight: 663.4 Da• Storage: 2 – 8 °C, keep dry and away from light• Shelf Life: 24 months from manufacture date (sealed)Quality & TestingEvery batch is independently tested by a certified third-party laboratory.
