Download COA (PDF)Handling & storage
Soluble in water; reconstitute in the solvent and to the concentration specified by your own protocol. The lyophilized powder should be stored at -20 C and protected from moisture and light. Reconstituted solutions are typically aliquoted to avoid repeated freeze-thaw cycles per your protocol. 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.
