Storage conditions for research peptides: temperature, desiccation, and stability
Peptide stability in storage is influenced by three primary environmental factors: temperature, moisture exposure, and light. Understanding how each factor contributes to degradation helps researchers maintain compound integrity between receipt and use.
Most lyophilized research peptides are best preserved at consistently low temperatures (commonly minus 20C) in a desiccated environment, minimizing exposure to ambient humidity that can accelerate hydrolytic degradation.
Repeated freeze-thaw cycling is a common and often underestimated source of peptide degradation. Where possible, researchers should aliquot reconstituted material to avoid repeated temperature cycling of the full sample.
Specific storage conditions for each compound in our catalog are listed on its product page, alongside batch and purity documentation.
