Supplied as a lyophilized powder in a sealed laboratory-grade glass vial. Intended for in-vitro and laboratory research applications only.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eResearch Context\u003c\/strong\u003e\u003cbr\u003eNAD⁺ 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.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003cbr\u003e• Sequence: Validated by mass spectrometry (MS\/MS)\u003cbr\u003e• Purity: ≥ 99% by HPLC\u003cbr\u003e• Form: Lyophilized powder\u003cbr\u003e• Molecular Weight: 663.4 Da\u003cbr\u003e• Storage: 2 – 8 °C, keep dry and away from light\u003cbr\u003e• Shelf Life: 24 months from manufacture date (sealed)\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eQuality \u0026amp; Testing\u003c\/strong\u003e\u003cbr\u003eEvery batch is independently tested by a certified third-party laboratory.
