Start with the product
Compound-specific information always comes first.
The correct storage conditions and acceptable storage period depend on the compound, formulation, packaging and research protocol. The guide below summarises the general information supplied for the catalogue.
Control temperature
Use the product-specific packaging and protocol to determine the correct environment.
Limit avoidable exposure
Moisture, direct light, agitation and repeated temperature changes should be minimised.
Overview
Plan the handling sequence before opening the product.
A controlled workflow reduces unnecessary exposure and helps researchers follow the conditions stated on the product packaging.
General principle
A universal expiry period should not be applied across all compounds. Stability is peptide and formulation dependent.
Unreconstituted format
Lyophilised peptide storage.
Peptides supplied as a freeze-dried powder should be stored at −20°C or below for long-term storage where applicable to the individual compound.
01
Keep sealed
Protect the vial from moisture, heat and direct light.
02
Equilibrate before opening
Allow the vial to reach room temperature after removal from cold storage to help minimise condensation.
03
Avoid fluctuations
Do not subject the product to unnecessary temperature movement.
After reconstitution
Reconstituted solutions are generally less stable.
Where appropriate for the compound and protocol, reconstituted solutions should be refrigerated at 2–8°C and protected from direct light.
01
Minimise agitation
Handle the preparation carefully and avoid unnecessary movement.
02
Use aliquots where needed
For frozen storage protocols, divide into suitable aliquots to reduce repeat freeze-thaw cycles.
03
Use stability data
Refer to compound-specific data rather than applying one universal storage period.
Environmental control
Protect products from avoidable exposure.
Moisture, heat and direct light are repeated variables to control across the supplied guidance.
Temperature control
Avoid repeated movement between environments.
Plan the laboratory workflow so the product is only removed when needed and returned promptly to the required conditions.
Responsible use
Laboratory research purposes only.
