Assay results
Every line the release panel ran for this lot, with the method, the acceptance criterion and the measured value — not a pass mark alone.

|---|---|---|---|---|
| RP-HPLC (UV 214 nm) | Purity (area %) | ≥ 99.0 % | 99.63 % | Pass |
| LC-MS (ESI+) | Identity — observed mass | 663.43 ± 1.0 Da | 663.25 Da | Pass |
| Amino acid analysis | Net peptide content | ≥ 80.0 % | 89.8 % | Pass |
| Karl Fischer | Water content | ≤ 8.0 % | 4.50 % | Pass |
| Ion chromatography | Residual TFA | ≤ 1.0 % | 0.14 % | Pass |
| LAL kinetic chromogenic | Bacterial endotoxin | < 5.0 EU/mg | < 0.36 EU/mg | Pass |
| USP <71> membrane filtration | Sterility | No growth | No growth | Pass |

Handling for this lot
- Appearance
- White to pale yellow lyophilised powder
- Storage
- -20 °C, desiccated. Hygroscopic — reseal immediately after opening.
- Reconstitution
- Prepare fresh. Aqueous NAD+ hydrolyses measurably within days even refrigerated, and the hydrolysis product inhibits sirtuins.
