Download COA (PDF)Handling & storage
Lyophilized powder. Reconstitute per your own protocol; the peptide is commonly dissolved in sterile water or an appropriate aqueous buffer, with brief gentle mixing and avoidance of vortexing. Store the lyophilized powder at -20 C; after reconstitution, store at 2-8 C for short-term use or aliquot and store at -20 C or below to limit freeze-thaw cycles. Allow vials to equilibrate to room temperature before opening to reduce condensation. Any downstream handling is performed by the buyer according to their own laboratory protocol and applicable safety practice.
