Peptide laboratory storage should be planned to minimize moisture, light, heat, and repeated freeze-thaw exposure. The most appropriate conditions depend on the peptide’s chemistry, formulation, and the manufacturer’s documentation.
Common storage practices
- Keep containers tightly sealed to limit moisture uptake and contamination.
- Protect from light by using opaque containers or secondary wrapping when needed.
- Store at a stable temperature according to the COA, product label, or internal SOPs.
- Avoid frequent temperature cycling by organizing aliquots for planned use.
- Record storage dates and conditions in laboratory inventory systems.
For research programs, storage decisions should be based on the peptide sequence, salt form, solvent compatibility, and any stability data supplied with the product documentation. If a COA includes storage guidance, it should be treated as the primary reference. Labs should also use validated handling procedures and limit sample exposure during transfers.
