- −80°C (ultra-low freezer)
- 24+ months
- Not recommended (ice crystal formation damages protein structure)
- Minimal. Near-zero chemical activity
- Ideal for long-term archival storage of unopened lyophilised peptides; excessive for routine use
- −20°C (standard freezer)
- 12–24 months
- Not recommended (requires freeze-thaw cycles)
- Minimal in lyophilised state; freeze-thaw degrades reconstituted peptides
- Standard storage for unopened lyophilised SS-LUP-332; move to refrigeration after reconstitution
- 2–8°C (refrigerator)
- Not recommended long-term
- 28 days (bacteriostatic water) / 14 days (sterile saline)
- Slow hydrolysis and oxidation; microbial growth if non-preserved
- Mandatory for reconstituted peptides; too warm for long-term lyophilised storage
- 15–25°C (room temperature)
- Weeks to months depending on humidity
- 24–72 hours before significant potency loss
- Rapid oxidation, deamidation, aggregation
- Unacceptable for any storage beyond brief ambient exposure during reconstitution
- Above 30°C (elevated heat)
- Days to weeks
- Hours
- Accelerated denaturation and irreversible aggregation
- Complete loss of bioactivity; discard immediately
