- Lyophilised at −20°C (sealed, desiccated)
- 24 months
- Moisture infiltration → partial reconstitution
- Long-term inventory storage
- Desiccant replacement every 6 months
- Lyophilised at 4°C
- 6 months
- Residual moisture → methionine oxidation
- Short-term benchtop access
- Must remain sealed. No repeated opening
- Reconstituted at 2–8°C (bacteriostatic saline)
- 28 days
- Methionine oxidation in aqueous solution
- Multi-dose vial for repeated use
- Light protection + temperature stability
- Reconstituted at −20°C (frozen)
- Not recommended
- Ice crystal formation → loss of helical structure
- None. Freezing destroys activity
- Do not freeze reconstituted peptide
- Room temperature (any form)
- <72 hours
- Rapid oxidation + aggregation
- Emergency short-term only during transport
- Single-use. Discard after 3 days
