Lyophilized versus reconstituted storage, cold-chain basics, and how to preserve stability across a research timeline.
In lyophilized form, most peptides are stable for extended periods when kept cold and dry. Long-term storage is usually at -20°C or lower, protected from light and moisture.
Once reconstituted, peptides are less stable and are generally kept refrigerated and used within a shorter window. Minimizing freeze-thaw cycles helps preserve integrity.
