Specifications

Reconstitution & storage (laboratory handling)

Store the lyophilised vial at -20C, protected from light and moisture, until use. For laboratory reconstitution, bacteriostatic water is commonly used as a solvent. Once reconstituted, keep the solution refrigerated at 2-8C and minimise freeze-thaw cycles. Use our peptide reconstitution calculator to determine concentration and volumes.
