Why Cold-Chain Handling Matters for Peptide Stability
Peptides are sensitive biological molecules. Even a well-manufactured, high-purity batch can degrade if it is exposed to inappropriate temperatures during storage or transit — which is why cold-chain handling is a core part of how research peptides should be supplied.
What Can Go Wrong Without It
Repeated temperature fluctuation, prolonged heat exposure, or freeze-thaw cycling can all contribute to peptide fragmentation and loss of structural integrity, even before a vial is opened.
Storage Guidelines
| Type | Lyophilised (unopened) | Reconstituted |
|---|---|---|
| Most peptides | Up to 48 months at -20°C | 2–8 weeks at 2–8°C |
These are general guidelines — always check the specific product page for compound-specific storage advice.
How We Handle Shipping
