Peptides are sensitive molecules, and how they’re stored directly affects their stability. In lyophilized (freeze-dried) powder form, most research peptides are relatively stable for extended periods when protected from heat, light, and moisture — typically in a freezer.
Once reconstituted into solution, peptides become more fragile and should be refrigerated and used within a shorter window. Repeated temperature swings and exposure to air can degrade the molecule, so avoiding repeated freeze-thaw cycles helps preserve integrity.
Good lab practice includes labeling vials with the reconstitution date, keeping desiccant with stored powder, and minimizing time at room temperature. Proper handling protects both your materials and the validity of your data.
