Why this one
Precursors are everywhere. The cofactor is what enzymatic work actually needs — sirtuins, PARPs and the rest consume NAD⁺ directly, and no salvage step belongs between your assay and the substrate.
Supplied for assays that consume or regenerate the cofactor, redox ratio measurement, and salvage and consumption pathway work.
Where it shows up in the literature
Redox biologyNAD⁺/NADH ratio measurement in cell and tissue lysates.
Sirtuin enzymologyDeacetylase assays requiring NAD⁺ as substrate.
PARP activityDNA damage response assays consuming cellular NAD⁺.
Salvage pathwaysFlux through nicotinamide and NMN-dependent routes.

Handling
Store sealed vials at 2–8°C for short-term use, or at −20°C for long-term storage, and protect from light. Reconstitute with the diluent your protocol specifies; bacteriostatic water is the common choice where a vial will be entered more than once.
Allow refrigerated material to reach room temperature before opening, and avoid repeated freeze-thaw cycles once in solution.
Certificate of analysis
Every lot is tested by an independent ISO-accredited laboratory. The lot number on your vial resolves at the testing laboratory directly, so the purity figure never has to come from the party selling it to you.
