Recommended Laboratory Storage Conditions
Lyophilized Powder: Store at 4°C (39°F) protected from light and moisture. Stable for extended periods under these conditions.
Reconstituted Solution: After reconstitution with bacteriostatic water, refrigerate at 2–8°C. Stable for approximately 1 month. Do not freeze.
Handling: Avoid vigorous shaking or agitation during reconstitution — direct solvent gently down the side of the vial to prevent peptide degradation.
