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.

Handling for this lot
- Appearance
- Blue lyophilised cake — the copper complex
- Storage
- -20 °C lyophilised, protected from light. Copper complexes are photosensitive.
- Reconstitution
- Non-chelating diluent only. Citrate or EDTA buffers will strip copper from the complex and, worse, release free copper that oxidises the other two peptides.
