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.
| Method | Parameter | Specification | Result | |
|---|---|---|---|---|
| RP-HPLC (UV 214 nm) | Purity (area %) | ≥ 98.0 % | 98.59 % | Pass |
| LC-MS (ESI+) | Identity — observed mass | 3647.20 ± 1.0 Da | 3647.19 Da | Pass |
| Amino acid analysis | Net peptide content | ≥ 80.0 % | 91.4 % | Pass |
| Karl Fischer | Water content | ≤ 8.0 % | 1.93 % | Pass |
| Ion chromatography | Residual TFA | ≤ 1.0 % | 0.27 % | Pass |
| LAL kinetic chromogenic | Bacterial endotoxin | < 5.0 EU/mg | < 0.26 EU/mg | Pass |
| USP <71> membrane filtration | Sterility | No growth | No growth | Pass |
| Visual / USP <790> | Appearance | White to off-white cake, free of visible particulates | Conforms | Pass |
| Thiol conjugation efficiency | Maleimide integrity | ≥ 90.0 % | 96.3 % | Pass |
Handling for this lot
- Appearance
- White lyophilised cake
- Storage
- -20 °C, desiccated and moisture-protected. Moisture hydrolyses the maleimide.
- Reconstitution
- Reconstitute immediately before use where possible. Conjugation efficiency declines in solution as the maleimide hydrolyses.
