Storing Research Peptides: Temperature, Light and Stability

Correct storage is one of the most overlooked variables in peptide research. Lyophilised (freeze-dried) peptides are relatively stable in powder form, but handling and storage conditions materially affect integrity once a vial is opened or reconstituted.

Lyophilised storage: In powdered form, most research peptides are best kept frozen at around -20C in a dry, dark environment. Short periods at refrigerator temperature (2-8C) are generally well tolerated during handling and shipping.

After reconstitution: Once reconstituted with bacteriostatic water, keep the vial refrigerated at 2-8C and protected from light. Some compounds are particularly light-sensitive, including the copper peptides GHK-Cu and AHK-Cu, and SS-31.

Bacteriostatic water: The benzyl alcohol preservative in bacteriostatic water allows it to be stored at room temperature, sealed or opened, rather than refrigerated.

Reconstituted shelf life varies by compound and storage conditions. Researchers should determine suitability for their own work. All Revexa products are supplied strictly for laboratory research use only, and are not for human or veterinary use.
