STORAGE & HANDLING
Pept Australia
A practical storage and handling reference for research peptides in the Australian climate.
Heat is the local variable
Most peptide storage guidance is written for temperate northern hemisphere conditions. An Australian summer, particularly in the north and west, puts a delivery van interior well above anything those guidelines assume. Lyophilised powder tolerates that far better than solution does, which is the single most useful fact for planning around it.
Three States, Three Rules
Sealed and Lyophilised
Freeze for long-term storage, shielded from light and humidity. Short ambient excursions in transit are generally tolerated; repeated freeze-thaw cycles are not helpful.
Reconstituted
Refrigerate at two to eight degrees Celsius, away from light, and treat as short-lived. This is the state where ambient heat does real damage quickly.
In Transport
Moving reconstituted material between sites is where most protocols come unstuck. A passive gel pack drifts within hours; an actively cooled case holds a set point.
On arrival
Move sealed vials into cold storage promptly rather than leaving the consignment on a bench. Record the batch number against your own inventory at the same time, so that when you later pull the certificate of analysis you can tie it to the specific vial used in a given experiment. That single habit resolves most provenance questions before they arise.
Storage and reconstitution supplies
Research Use Only. General handling information for laboratory materials, not a validated protocol. Always follow the storage conditions specified by your own method. Not medicines and not supplied for human or veterinary use.
