Maintaining the integrity of peptides requires strict attention to storage conditions and reconstitution protocols. These compounds are highly sensitive to heat, light, moisture, and contamination. Even minor handling errors can compromise purity and reduce efficacy.
Proper storage begins upon receipt. Lyophilized (freeze-dried) peptides should be refrigerated between 2°C and 8°C. For long-term storage, many compounds remain stable in a standard freezer. Exposure to high temperatures or fluctuating conditions can degrade molecular structure and increase the risk of impurity formation.
Once reconstituted, peptide stability depends on the solvent used and the sterility of handling. Most researchers use bacteriostatic water (0.9% benzyl alcohol in sterile water) to preserve integrity and minimize microbial growth. Always use sterile syringes and alcohol-prepped surfaces during preparation. Mix slowly — avoid shaking or aggressive agitation.
Key considerations include:
- Using the correct solvent and concentration
- Mixing slowly and avoiding agitation
- Labeling vials with date and dose concentration
- Refrigerating reconstituted peptides (2°C to 8°C)
- Discarding any solution that appears cloudy, discolored, or contains particulates
