Proper storage is essential for maintaining peptide stability and preventing degradation, oxidation, or contamination. Peptides should be kept in cold, dry, and light-protected conditions as soon as they are received. For short-term storage (days to weeks), refrigeration at 4°C (39°F) is generally sufficient. Lyophilized peptides are typically stable at room temperature for several weeks, allowing for near-term experimental use. For long-term storage (months to years), peptides should be placed in a deep freezer at –80°C (–112°F) to ensure maximum preservation. Avoid repeated freeze-thaw cycles, and do not use frost-free freezers, as temperature fluctuations can accelerate degradation.

Peptides are sensitive to oxidation and moisture. When removing a peptide from frozen storage, allow the vial to reach room temperature before opening to prevent condensation on the peptide or inside the container. Limit exposure to air as much as possible. After removing the required amount, containers should be resealed promptly and, when available, sealed under a dry, inert gas such as nitrogen or argon. Peptides containing cysteine (C), methionine (M), or tryptophan (W) are especially prone to oxidative changes. To reduce degradation risks, it is recommended to aliquot peptides into single-use portions to avoid repeated freeze-thaw cycles.

Peptide solutions are less stable than lyophilized peptides and are more vulnerable to microbial and chemical breakdown. Sequences containing Cys, Met, Trp, Asp, Gln, or N-terminal Glu are particularly unstable in solution. If peptides must be stored in solution, use sterile buffers at pH 5–6 and divide the solution into aliquots immediately. Peptide solutions stored at 4°C (39°F) are generally stable for up to 30 days, but unstable sequences should remain frozen when not in use. Long-term storage in solution is not recommended.
