Download COA (PDF)Handling & storage
Supplied as a lyophilized powder. Reconstitute per your own protocol; the peptide is typically dissolved in sterile water or a comparable aqueous buffer of your choosing, with concentration and diluent determined by the researcher. Store the lyophilized powder at -20 C and protect from light and moisture; prepare aliquots of reconstituted solution and store at -20 C to limit freeze-thaw cycles. Allow vials to equilibrate to room temperature before opening to minimize condensation. Any downstream handling is performed by the buyer according to their own laboratory protocol and applicable safety practice.
