How Peptides Should Be Stored in Research Laboratories
Lyophilized research peptides are generally stored frozen, commonly at -20 °C, protected from light and moisture. After reconstitution, solutions are typically refrigerated and used within the period supported by supplier documentation. Repeated freeze-thaw cycles and prolonged room-temperature storage should be avoided.

Handling lyophilized material
Allow sealed vials to equilibrate to room temperature before opening to reduce condensation, which introduces moisture into the cake.
After reconstitution
Reconstituted material is less stable than the dry form. Where longer storage is required, aliquoting reduces freeze-thaw exposure of the whole stock.
Documentation over generalisation
Storage guidance varies by molecule and formulation. The storage information supplied with a specific material takes precedence over general rules of thumb.
