- 1.Temperature
*For short-term storage (days to weeks), a standard refrigerator (2–8°C) is usually sufficient.
*For medium- to long-term storage (months to years), lyophilized vials should be kept in a -20°C freezer. If conditions permit, ultra-low temperature storage at -80°C can further extend the stability period.
- 2.Protection from Light and Moisture
UV and visible light can catalyze the oxidation of certain amino acid residues (especially tryptophan, tyrosine). Vials should be stored in their original packaging or opaque containers. Additionally, moisture is the primary enemy of lyophilized powders. Absorbing moisture reintroduces water necessary for hydrolysis; therefore, reconstitution operations should be performed swiftly, and the vial must be sealed tightly.
- 3.Avoid Unnecessary Temperature Cycling
When removing vials from the freezer, the best practice is to allow the sealed vial to reach room temperature before opening. This prevents condensation from forming on the inner walls of the vial, which would otherwise introduce moisture and promote degradation.
- 4.Do Not Freeze Solutions Reconstituted with Bacteriostatic Water
If reconstituted with bacteriostatic water for parenteral use (containing 0.9% benzyl alcohol as a preservative), the solution must not be frozen. Freezing can disrupt the distribution of benzyl alcohol and potentially cause phase separation. Furthermore, the formation of ice crystals exerts mechanical shear stress on peptide molecules, accelerating aggregation and degradation. Solutions prepared with bacteriostatic water should only be refrigerated and used within their valid shelf life.
- 5.Storage of Solutions Reconstituted with Sterile Water
If reconstituted with preservative-free sterile water for parenteral use, the solution lacks antimicrobial protection, posing a higher risk of microbial contamination and resulting in a shorter usable lifespan under refrigeration (typically only a few days). If longer storage is required in this case, the solution can be aliquoted into small volumes and frozen in a single batch to minimize repeated freeze-thaw cycles.
- 6.Avoid Repeated Freeze-Thaw Cycles
Regardless of the solvent used, repeated freezing and thawing is one of the most destructive processes for reconstituted peptides. Each freeze-thaw cycle induces peptide aggregation and loss of bioactivity. If freezing is necessary, always aliquot the solution into single-use vials, following the principle of "thaw one aliquot, use it entirely."
- 7.Maintain Stability and Cleanliness
When refrigerating, place vials securely in the most temperature-stable area of the refrigerator (typically the middle shelf, rather than the frequently opened door racks). Always use aseptic techniques when withdrawing the solution, and avoid repeated contamination of the liquid inside the vial by the needle.
