Buy NAD+ for laboratory research
Buy NAD+ in 500 mg and 1000 mg single-vial formats for laboratory research. The listing is for oxidized nicotinamide adenine dinucleotide, also written NAD plus, rather than an NADH listing.
Availability: The 1000 mg option is out of stock. Select an available option shown above.
What researchers investigate
NAD+ helps transfer electrons in biochemical reactions and is also consumed by enzymes including sirtuins, PARPs and CD38. It is a dinucleotide, not a peptide. In an experiment, NAD+, NADH and the ratio between them answer different questions; adding extracellular NAD+ does not by itself establish the concentration inside a cell or its mitochondria.
How to interpret a laboratory result
Separate cofactor identity, reduced-form contamination and assay interference from the biological question. Use calibration standards and a suitable analytical method when quantifying NAD pools. Record whether a result represents total material, a particular compartment or an enzyme-coupled signal.
Choosing a research vial
Start with the molecular identity and the question your laboratory needs to answer. Choose an amount that fits the planned analytical work, controls and repeat measurements. A higher-mass vial does not mean higher purity or stronger activity. For a new workflow, separate a small compatibility assessment from the material reserved for the main study. Listed selector values: 1000 mg / 500 mg.
Purity, identity and lot documentation
Review the current certificate-of-analysis library and match the compound, amount and lot identifier to the delivered material. HPLC area purity describes the relative chromatographic signal under the reported method; mass spectrometry supports molecular identity. Neither result alone establishes net content, sterility, endotoxin status or biological activity. If the matching report is pending or unavailable, request documentation before treating those properties as verified.
Storage and laboratory preparation
Follow the current product label and lot-specific handling instructions. Keep sealed material protected from unnecessary moisture, heat and light. For cold-stored sealed vials, allow the container to equilibrate while closed before opening to reduce condensation. Once a solution is prepared, validate its solvent, concentration, container and holding time for the intended assay. Use separate aliquots when appropriate to limit repeated handling and freeze-thaw exposure. Appearance is not a substitute for an analytical stability assessment.

Lot-specific documentation snapshot
The public COA library lists a 500 mg NAD+ record for lot SRL-NAD-101, reporting chromatographic purity of 99.65%. This result describes that named report only. It does not establish the identity, amount, sterility, or purity of a different lot or product option.
Before procurement, match the compound and lot on the current report to the material under review. Our COA reading guide explains how to assess the analytical method and limitations. Contact support with a lot number if you need clarification. Listed-lot availability may change.
