Laboratory Peptides: Practical Research Guide | Peptide Intel Hub
A practical guide to handling lyophilised research peptides — covering reconstitution, storage, in-use stability and basic assay considerations.
Reconstitution basics
Most lyophilised peptides reconstitute with bacteriostatic water. Add solvent slowly down the vial wall; swirl, do not shake. Avoid direct contact with the lyophilised cake.
Cold chain
Lyophilised storage at 2–8°C is standard. Long-term archive storage may use −20°C. Reconstituted product stays refrigerated and is used within the COA's stated window.
Assay considerations
Peptide content (not just mass) drives quantitative accuracy. Cross-reference the COA's peptide-content figure when preparing working stocks.
Frequently asked questions
Can I freeze reconstituted peptide?+
Some peptides tolerate a single freeze-thaw cycle; many do not. Defer to the COA and your internal SOP.
