NAD+ (β-Nicotinamide Adenine Dinucleotide) – High Purity Premium Cofactor API

Product Overview NAD+, full name β-Nicotinamide Adenine Dinucleotide, also called oxidized Coenzyme I, DPN+. It is an essential endogenous pyridine dinucleotide coenzyme existing in all living cells, circulating reversibly between oxidized NAD+ and reduced NADH forms to undertake hydride ion and electron transfer in cellular tricarboxylic acid cycle, oxidative phosphorylation and energy metabolism pathways. Besides redox cofactor function, it serves as substrate for Sirtuins, PARPs and CD38 enzymes, participating in DNA damage repair, protein acetylation modification, cell aging regulation, calcium signal transduction and immune cell function modulation. It shows distinct ultraviolet absorption characteristics: NAD+ only has absorption peak at 260 nm, while NADH has characteristic absorption at 340 nm, widely adopted for enzyme activity quantitative detection.

It is applied in laboratory research including cellular energy metabolism assay, dehydrogenase activity determination, oxidative stress research, DNA repair mechanism, sirtuin aging pathway exploration, enzyme kinetic analysis and in vitro biochemical reaction kit preparation. It is extensively adopted in redox signaling pathway verification, cell senescence pharmacology evaluation and diagnostic reagent raw material development experiments.

Adopting optimized biological fermentation combined with multi-stage chromatographic purification technology, the product features excellent water solubility, low impurity content and stable chemical structure after dissolution in aqueous buffer. CAS Number: 53-84-9
