Storage temperature and peptide stability

Temperature is one of the main factors in peptide stability. Lower temperatures generally slow the chemical and physical changes that can affect a peptide over time.

Lyophilized peptides are commonly stored cold, with many laboratories using freezer storage for longer holding periods.

Once reconstituted, a peptide is in solution and is usually less stable than the dry powder, so it is typically kept cold and used within a limited window.

Preparing small aliquots reduces repeated freezing and thawing, which can degrade material. Follow the storage guidance listed per product.
