If you're running sirtuin activation assays or mitochondrial function studies, thing that kills your experiment is degraded NAD+—so starting with >99% purity matters more than you'd think, and this batch checks that box with HPLC-verified results.
It's a, soluble in water, and you'll want to reconstitute it fresh—after that it's stable at 2-8°C for a week or so, but we usually stock it and ship within 2-3 business days (confirm lead time for larger orders).
Molecular weight is 663.43 g/mol, CAS 53-84-9, and the powder itself handles fine at room temp before reconstitution—just keep it dry and away form moisture.
Most buyers go with the 100mg vial for pilot runs, but we also offer 500mg and 1g formats if you're scaling up—just note this is research-only, not for human use, and it's not suited for cell culture work without proper buffer optimization.
What it does is bind to enzymes like sirtuins and PARPs, basically shuttling electrons in redox reactions—so if your protocol demands tight control over NAD+/NADH ratios, this is better than reagent-grade alternatives for that.
One thing you might not think to ask: teh powder can clump if exposed to humidity, so we pack it with a desiccant and foil pouch—it's a small detail, but it saves you headaches during reconstitution.
