Download COA (PDF)Handling & storage
Supplied as a lyophilized powder. Reconstitute per your own validated protocol; bacteriostatic or sterile water is commonly used as the diluent, and peptides of this size are typically dissolved by adding solvent gently against the vial wall and swirling rather than vortexing. Store the sealed lyophilized powder at -20C, protected from light and moisture; after reconstitution, store at 2-8C and use within the timeframe established by your own stability data. Avoid repeated freeze-thaw cycles. For research use only. Any downstream handling is performed by the buyer according to their own laboratory protocol and applicable safety practice.
