NAD+

Research context

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme central to redox biology. It is supplied as a research reagent for in-vitro enzymatic assays involving sirtuins, PARPs, and cellular energetics research. Not a peptide, but included for research workflows that pair peptide studies with NAD+ metabolism.

Storage & stability

Store lyophilized at -20°C, desiccated.

Purity & testing standards

Each batch of NAD+ is analyzed by an independent third-party laboratory. Standard release testing includes reverse-phase HPLC at 220 nm (purity target ≥98% purity), electrospray mass spectrometry (identity confirmation), and endotoxin screening. Batch numbers on each vial resolve to a downloadable COA on this site.
