What is NAD+?

NAD+ (nicotinamide adenine dinucleotide) is a universal cellular coenzyme that shuttles electrons for energy production and serves as a substrate for enzymes that govern DNA repair, stress responses, and metabolic signaling (e.g., sirtuins and PARPs).

FAQ

How much is in each vial?

Each vial contains precisely the amount indicated on the label. For instance, a 10mg vial includes precisely 10mg of lyophilized peptide. Researchers may divide it into smaller fractions, such as four 2.5mg portions, while the total amount remains 10mg.

Does it come with instructions?

USA Peptides Direct products are designated for in vitro research. Prior to working with them, conduct thorough research. Our team will offer general assistance via text post-purchase.

What other supplies are needed?

Peptides come as lyophilized powder. They are not reconstituted, and any necessary bacteriostatic water or syringes must be obtained separately for research purposes.

How long does a vial last?

Peptides remain stable for up to 2 years in lyophilized powder form. After reconstitution, refrigerate and expect stability for about 2 months.

Is this the oxidized form?

Yes. This product is NAD+(oxidized). For reduced NADH or NADP(H), see our catalog.

What purity is provided?

Each vial is ≥99% by HPLC with MS identity confirmation; third-party testing is performed on every lot (COA via QR).

How should I reconstitute it?

Use sterile water or a neutral, compatible buffer; gently invert to dissolve. Prepare fresh working solutions, aliquot, and avoid alkaline pH and repeated freeze–thaw.

Which in-vitro assays is NAD+ commonly used in?

Typical RUO uses include dehydrogenase kinetics (340 nm), sirtuin and PARP assays, NAD+-dependent ligase reactions, and LC–MS method development for dinucleotides.
