Proper Storage of Research Peptides: A Complete Guide

Proper storage of research peptides is essential to maintain their stability, purity, and integrity over time. Mishandling can lead to degradation, aggregation, or loss of potency — compromising your research.

Lyophilized (Freeze-Dried) Peptides

Most peptides ship in lyophilized form. Store them in a cool, dry environment — ideally refrigerated at 2–8°C. Kept properly, lyophilized peptides can remain stable for years.

Reconstituted Peptides

Once reconstituted with bacteriostatic water, peptides become significantly less stable. Store reconstituted solutions refrigerated (2–8°C) and use within a defined timeframe per your protocol. Avoid repeated freeze-thaw cycles.

Light and Moisture

Peptides are sensitive to UV light and moisture. Keep vials sealed, protected from light, and in a controlled environment.

Key Takeaway

Always follow the storage instructions on the label. When in doubt, refrigerate. Consistency in storage conditions ensures your results are reproducible.
