What is NAD+?
NAD+ is the oxidized form of nicotinamide adenine dinucleotide, a coenzyme present in every living cell. It accepts electrons in redox reactions and is a substrate for sirtuins and PARP enzymes.
Key facts
- Compound class: Nicotinamide adenine dinucleotide (coenzyme)
- Molecular formula: C21H27N7O14P2
- Molecular weight: 663.4 g/mol
- Form: Lyophilized powder

In laboratory research
Researchers use NAD+ in studies on cellular energy metabolism, DNA repair, sirtuin activity and age related decline of NAD+ pools.
Related compounds
Within our cellular research collection, this compound is most often compared with MOTS-c, a mitochondrial derived peptide, Epithalon, a synthetic tetrapeptide (Ala-Glu-Asp-Gly) and Thymalin, a thymic peptide complex. Running related compounds side by side, with matched vehicle controls and the same assay conditions, makes it easier to attribute differences in a readout to the compound itself rather than to handling or batch effects.
Mitochondrial peptides, telomere and thymic peptides, and redox cofactors used in research on cellular energy, senescence and immune signaling. Each lot is supplied with documentation for laboratory records.
Choosing a size
This compound comes in 3 sizes. Smaller vials suit pilot experiments and method development, while larger vials lower the cost per unit for longer studies and replicate runs.
- 100mg: $48.99, about $0.49 per mg
- 500mg: $74.99, about $0.15 per mg
- 1000mg: $119.99, about $0.12 per mg
Moving from the 100mg vial to the 1000mg vial reduces the cost per mg by roughly 76 percent. If a study needs several smaller aliquots, one larger vial reconstituted and divided under your lab protocol is often the most economical option.
Every size ships as a lyophilized powder in a sealed vial. Reconstitute with bacteriostatic water or, where an acidic diluent is recommended, acetic acid water.
Working with it in the laboratory
Allow the sealed vial to reach room temperature before opening. Add the diluent slowly down the side of the vial, then swirl gently until the lyophilized powder has fully dissolved. Most researchers use bacteriostatic water; use acetic acid water only where the data for your compound calls for an acidic diluent.
Label the vial with the concentration, the date and the batch number, then store it as described below. For long studies, dividing the solution into single use aliquots avoids repeated freeze and thaw cycles. Our peptide research guide includes a worked example for calculating concentration.
Storage and stability
Store sealed vials at -20 °C, protected from light, for long term stability. Allow the vial to reach room temperature before opening to prevent condensation. After reconstitution, keep the solution refrigerated and avoid repeated freeze and thaw cycles.
Batch documentation
Every lot carries a batch number that links it to a certificate of analysis recording identity by mass spectrometry and purity by HPLC. Request the COA for your batch at any time, and keep it with your lab records alongside the concentration and date of reconstitution.
