NAD+ (nicotinamide adenine dinucleotide) is an oxidized dinucleotide cofactor supplied exclusively for controlled in-vitro laboratory research involving redox chemistry, cofactor-dependent enzyme systems, and NAD+/NADH analytical methods.
Each vial contains 1000mg of lyophilized NAD+. The material is independently analyzed for identity and purity, with batch-specific documentation available through the NordSci COA Library.
NAD+ may be incorporated into controlled laboratory experiments examining oxidation-reduction reactions, substrate utilization, enzyme kinetics, cofactor availability, and analytical assay performance. Qualified researchers are responsible for establishing appropriate concentrations, controls, analytical methods, and experimental protocols.
NordSci provides lot-specific documentation to facilitate material verification, laboratory inventory management, and batch traceability.
The primary concern for peptide researchers today is product purity. Nord-sci guarantees our product purity by performing independent testing of our products and providing those certifications for our customers in our product descriptions.

All products are produced using lyophilization (freeze-drying), a preservation method that allows peptides to remain fully stable during shipping for approximately 3-4 months. Once a peptide has been reconstituted with bacteriostatic water, it must be refrigerated to maintain integrity. After reconstitution, peptides typically remain stable for up to 30 days when stored properly.
Lyophilization, also referred to as cryodesiccation, is a specialized dehydration process in which peptides are first frozen and then exposed to a low-pressure environment. This causes the water within the vial to transition directly from a solid to a vapor (sublimation), leaving behind a dry, crystalline white material known as a lyophilized peptide. In this powdered form, peptides may be safely stored at room temperature until they are ready to be reconstituted with bacteriostatic water.
After delivery, peptides should be protected from heat and light. If use is expected within the near future (whether days, weeks, or a few months) refrigerated storage below 4°C (39°F) is generally sufficient. Lyophilized peptides are commonly stable at room temperature for several weeks or longer, making short-term ambient storage acceptable when use is anticipated within that timeframe.
For extended storage, ranging from several months to multiple years, freezing is strongly recommended. Storage at -80°C (-112°F) offers optimal long-term stability and helps preserve peptide structure and quality over time.

NAD+ is the oxidized component of the NAD+/NADH redox pair. In controlled laboratory systems, this pair is examined in relation to electron-transfer reactions, biochemical assay development, and the characterization of cofactor-dependent enzymes.
NAD+ also serves as a substrate in laboratory investigations of enzyme families that include poly(ADP-ribose) polymerases, sirtuins, and NAD-consuming glycohydrolases. Researchers may measure enzyme activity, substrate utilization, reaction kinetics, and changes in NAD+ or NADH concentrations under defined experimental conditions.
Because NAD+ participates in multiple biochemical reactions, experimental work requires validated methods, appropriate reference materials, predefined endpoints, and suitable controls. Observations remain specific to the laboratory models and conditions evaluated.
NAD+ is used in controlled laboratory investigations involving redox reactions and cofactor-dependent biochemical processes. NAD+, NADH, and the NAD+/NADH ratio may be measured as analytical variables in cell-free or in-vitro systems.
Applicable methods may include enzyme assays, spectrophotometry, chromatography, mass spectrometry, and other validated analytical procedures. Experimental designs should account for sample preparation, assay specificity, detection limits, reference standards, and control conditions.
NAD+-dependent enzymes are examined in laboratory models involving DNA-associated biochemical processes, chromatin-related mechanisms, and intracellular signaling pathways. These studies may characterize relationships between NAD+ availability and defined biochemical reactions without establishing diagnostic or therapeutic outcomes.
Laboratories should use appropriate controls to distinguish NAD+-dependent observations from solvent, vehicle, assay, or model-specific variables. Sample identification, storage records, analytical timepoints, and protocol deviations should be documented to facilitate reproducibility.
NAD-related measurements appear in preclinical research frameworks examining changes in redox state, cofactor availability, and enzyme activity over time. These investigations evaluate measurable biochemical variables under defined laboratory conditions.
NordSci NAD+ is not offered for anti-aging, longevity, wellness, performance, or consumer applications. It is supplied exclusively as an in-vitro laboratory research material. Findings from experimental models do not establish clinical efficacy, consumer benefits, or an appropriate use in humans or animals.
Each NAD+ lot is independently analyzed for identity and purity. The applicable Certificate of Analysis may include HPLC results, mass spectrometry data, or other analytical findings associated with the tested batch.
Typical laboratory quality-control practices include:
Analytical findings apply only to the tested batch and the methods identified in the corresponding documentation. No dosing, injection, application, or administration guidance is provided.
Laboratories should obtain NAD+ from suppliers that provide clear research-use restrictions, batch identification, storage information, and accessible analytical documentation.
NordSci supplies NAD+ as a research-grade biochemical for controlled in-vitro laboratory use. Batch-level traceability and COA availability allow laboratories to incorporate the material into established procurement, inventory, and quality-assurance systems.
