Concise, practical guidance for researchers handling lyophilized peptides — from reconstitution to storage to COA verification.
Lyophilized peptides should be reconstituted with bacteriostatic water (0.9% benzyl alcohol) using a slow injection along the inside wall of the vial. Avoid agitation that could denature the peptide; gently swirl until fully dissolved.
Unreconstituted vials are stable at –20 °C in their original sealed container away from direct light. Once reconstituted, store at 2–8 °C and use within the recommended window for the specific peptide.
Every batch ships with a certificate of analysis on request, listing peptide identity by mass spectrometry, purity by HPLC, and sterility per USP <71>. Cross-check the batch number on the vial against the COA before use.
