NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell, central to redox biochemistry, energy metabolism, and sirtuin enzyme activity. The lyophilized research-grade NAD+ supplied here is used for cellular and rodent research on NAD+-dependent biology. Supplied strictly for Research Use Only.
NAD+ is studied in preclinical research on sirtuin (SIRT1-7) activity, electron transport chain function, NAD+ salvage and de novo synthesis pathways, and cellular metabolism. All cited studies are conducted in cellular or rodent systems consistent with the molecule's RUO classification.
Research-grade NAD+ is supplied with batch-specific HPLC purity data and mass spectrometric identity confirmation, intended for controlled experimental conditions. Supplement-grade products do not require the same documentation and are not characterized to the same analytical standard.
