UV protection
Shielding peptides from ultraviolet light, which accelerates oxidation and degradation. Achieved through amber vials, opaque packaging, and dark storage conditions.

Why is UV protection important in peptide research?
Related Terms
A dark brown glass vial that filters UV and visible light to protect light-sensitive peptides from photodegradation. Standard for pharmaceutical peptide storage.
OxidationA chemical reaction that can damage methionine and cysteine residues in peptides, reducing activity. Oxidation is accelerated by light, heat, and oxygen exposure. Prevented by proper storage in amber vials with desiccant.
StabilityA peptide’s resistance to chemical degradation over time. Affected by temperature, pH, light, and oxidation. Lyophilized peptides are most stable; reconstituted peptides should be refrigerated and used within 28 days.
Peptide storageThe conditions required to maintain peptide stability and potency. Lyophilized peptides should be stored at -20°C for long-term or 2–8°C for short-term. Reconstituted peptides must be refrigerated and used within 28 days.
