How to Store Research Peptides

Proper storage of research peptides is essential for maintaining compound integrity and ensuring reliable experimental results. This guide covers standard storage practices used in laboratory environments across Australia. Lyophilised (freeze-dried) peptides should be stored in a cool, dry environment away from direct light. Before reconstitution, most peptides can be stored at room temperature for short periods, though refrigeration at 2–8°C is recommended for extended storage. For long-term preservation, unreconstituted peptides should be stored at -20°C or below. Once reconstituted with bacteriostatic water, peptides should be refrigerated at 2–8°C and used within a reasonable timeframe, typically within 4–6 weeks depending on the specific compound. Reconstituted peptides should never be refrozen, as freeze-thaw cycles can degrade the compound.
