NAD+ 500MG

Product Overview

NAD+ 500MG is a lyophilised nicotinamide adenine dinucleotide research reagent, supplied as white to off-white lyophilised powder in a 500mg catalogue presentation (SKU NJ500). This page describes the stated research identity and batch-oriented catalogue specification; it does not provide an administration protocol.

NAD+ is a central redox cofactor and substrate in cellular metabolism, DNA-repair signalling and enzyme regulation. Research spans biochemistry, cell biology and ageing-related pathway studies.

Research Context

The following themes summarise published research on the named molecule or components. They are research contexts, not claims about the supplied ExtolX batch.

Areas of Research

• redox and energy metabolism
• sirtuin and PARP-associated signalling
• DNA-repair and stress-response pathways
• cofactor quantification and metabolic-flux assays

Evidence Quality and Limitations

The literature is extensive at the pathway level, but results depend on the biological system, precursor status and analytical method. Product identity and performance require batch-specific verification.

Storage and Handling

As supplied: NAD+ is not a peptide. Keep the vial sealed, dry and protected from light at −20°C, subject to the batch-specific supplier documentation. Published reference data use the NAD+ free-acid form, but the exact chemical form of this ExtolX batch has not been confirmed.

In aqueous solution: The published free-acid reference advises against storage for more than one day. Because chemical-form and formulation agreement have not been established, prepare solution fresh where the validated method permits and do not assume a longer hold time. Record the solvent, concentration, preparation time, temperature and container used.

Compatibility Limitations

Do not infer solubility or stability from another peptide, blend, amount or pharmaceutical formulation. Use small-scale method development and appropriate analytical controls before committing valuable material.

Laboratory Safety

Handle only in an appropriately equipped laboratory by trained personnel. Use a task-specific risk assessment, suitable personal protective equipment and applicable safety documentation. Avoid ingestion, inhalation, skin contact and environmental release, and dispose of waste in accordance with local requirements.
