Proper storage protects the integrity of research peptides. This guide covers the basics of handling lyophilised and reconstituted material in a laboratory setting. It is about storage and stability only — it contains no dosing, administration, or usage instructions.
Lyophilised (freeze-dried) peptides
- Keep cool and dark. Sealed lyophilised vials are generally stored refrigerated for shorter periods and frozen for longer-term storage, away from light and humidity.
- Avoid temperature swings. Stable, consistent cold storage is better than repeated warming and cooling.
- Keep sealed until needed to limit exposure to moisture and air.
Reconstituted peptides
- Once a peptide is dissolved (for example, in bacteriostatic water for laboratory handling), it is typically refrigerated and is less stable than the dry powder.
- Minimise freeze–thaw cycles. Repeated freezing and thawing of solutions can degrade peptides.
- Protect solutions from light and keep them sealed.
General handling tips
- Record the batch number and date so you can match material to its COA.
- Label containers clearly, including the date prepared.
- Handle with clean technique appropriate to a laboratory environment.
Storage conditions vary by compound. Always follow the guidance appropriate to the specific peptide and your laboratory’s protocols.
Lab-tested peptides, shipped ready to store
Every batch arrives with a batch-matched COA and a documented ≥99% purity standard.
Frequently asked questions
How should I store lyophilised peptides?
Generally cool and dark — refrigerated for shorter periods, frozen for longer-term storage — kept sealed and away from light and moisture. Follow compound-specific guidance.
Do reconstituted peptides last as long as the powder?
No. Once dissolved, peptides are typically refrigerated and are less stable than the dry powder. Minimise freeze–thaw cycles.
Why avoid freeze–thaw cycles?
Repeated freezing and thawing can degrade peptides in solution, reducing integrity over time.
