NAD+ is a dinucleotide coenzyme, not a peptide - the oxidised form of nicotinamide adenine dinucleotide, central to redox reactions across essentially all cellular metabolism.
NAD+ is a dinucleotide coenzyme, not a peptide - the oxidised form of nicotinamide adenine dinucleotide, central to redox reactions across essentially all cellular metabolism.
It is the most hygroscopic item in the catalogue by a wide margin. Vials should be brought fully to room temperature before opening, since opening a cold vial condenses atmospheric moisture directly onto the powder and will degrade it.
Aqueous solutions are unstable at alkaline pH, where the nicotinamide-ribose bond hydrolyses. Solutions should be prepared fresh and kept at or below neutral pH.

Vials arrive lyophilized and sealed under nitrogen. Bring the vial fully to room temperature before breaking the seal — opening a cold vial condenses atmospheric moisture onto the cake.
Direct diluent gently against the inside wall of the vial rather than onto the cake, and allow the material to dissolve without agitation. Vortexing shears longer sequences and introduces air.
Lyophilized: -20 C, tightly sealed, desiccated. Reconstituted: 2-8 C, use within 14 days.
A full walkthrough is in the reconstitution guide, and the calculator will work out concentration and draw volume for this vial size.
Standard laboratory practice applies: appropriate personal protective equipment, no consumption, no administration to humans or animals, and disposal in accordance with institutional protocol and local regulation.
Per-lot laboratory certificate: pending. A reverse-phase HPLC purity report, an LAL bacterial endotoxin assay and a mass-spec identity confirmation for lot PS-8502026 have not been generated or published. PeptideSeed is working directly with its supplier to obtain genuine per-lot documentation and will publish it here, tied to this exact lot number, once it exists. New to reading these?

NAD+ is strongly hygroscopic. Opening a cold vial condenses moisture onto the powder and degrades it.
Aqueous NAD+ hydrolyses, particularly at alkaline pH. Prepare fresh where possible.
No - it is a dinucleotide coenzyme. It is stocked because it appears alongside the peptide catalogue in bench work.
NAD+ is supplied for in-vitro laboratory research only. It is not a drug, dietary supplement, food or cosmetic, is not approved by the FDA for any use in humans or animals, and no dosing guidance is published for it. Nothing on this page is a therapeutic, structure–function or health claim. Purchasers must be 21 or over and are responsible for compliance with all applicable law. Full terms of supply.
