- Lyophilised powder
- −20°C
- 2–3 years
- Sealed vial with desiccant in freezer-safe bag
- Critical. Use silica gel packets, replace every 6–12 months
- Longest viable storage method; requires manual-defrost freezer or lab-grade unit with stable temperature
- Reconstituted solution
- 2–8°C refrigerated
- 28 days maximum
- Amber glass vial, upright in main compartment (not door)
- Not applicable once in solution
- Standard protocol for active research use; discard after 28 days regardless of appearance
- Room temperature (lyophilised)
- 20–25°C ambient
- 7–14 days before significant degradation begins
- Original sealed vial
- Acceptable for short-term shipping only
- Emergency option only; not suitable for intentional storage beyond transit time
- Frozen reconstituted solution
- −20°C or lower
- Not recommended. Ice crystals cause irreversible aggregation
- N/A
- Freezing destroys tertiary structure; solution may look clear post-thaw but bioactivity is compromised
