NAD+ in Research: Redox Biology and Laboratory Methods

NAD+ (nicotinamide adenine dinucleotide) is one of the most studied coenzymes in cellular biology. It cycles between oxidized (NAD+) and reduced (NADH) forms, carrying electrons in the redox reactions that underpin energy metabolism and a wide range of enzymatic processes.

Identity and molecular data

• Compound: NAD+ (nicotinamide adenine dinucleotide)
• CAS: 53-84-9
• Molecular weight: approximately 663 Da
• Format: lyophilized powder in a sealed research vial

A batch Certificate of Analysis reports identity and reported purity for the specific lot supplied.

Redox biology in research

NAD+ research spans mitochondrial bioenergetics, sirtuin and PARP enzyme activity, and the broader study of cellular aging. The precursor pathways (NMN, NR) are compared elsewhere in our NAD+, NMN and NR overview; this article focuses on NAD+ itself as a redox cofactor used directly in laboratory assays and models.

Handling and documentation

NAD+ is sensitive to moisture and heat; keep material sealed and protected, following general storage guidance. As with any reference material, reported HPLC purity is a single measurement — review the full analytical scope, and confirm the lot number against the documentation.

The TagPep NAD+ 1,000 mg research vial ships with batch-linked documentation for laboratory research use only.
