Download COA (PDF)Supplied as a lyophilized powder. Reconstitute per your own protocol; the peptide is commonly dissolved in sterile water or bacteriostatic water, with mild buffers as needed for your workflow. Briefly centrifuge the vial before opening and allow it to reach room temperature prior to reconstitution. Store the lyophilized powder at -20 C and protect from light and moisture; store reconstituted aliquots at -20 C or below and avoid repeated freeze-thaw cycles. Not for human or veterinary use; not for consumption; not for diagnostic or therapeutic use. Any downstream handling is performed by the buyer according to their own laboratory protocol and applicable safety practice.
