Peptide Storage

Lyophilised peptides should be stored at –20°C or below, protected from moisture and light, in their original sealed vial with desiccant present in the shipping container.

Once reconstituted, most peptides are stable for 2 to 4 weeks at 2–8°C. Bacteriostatic water is preferred over sterile water for extended shelf life. Do not refreeze reconstituted peptides — freeze-thaw cycles disrupt structural integrity and reduce yield.
