Quality Control

Our Urotensin I is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and mass spectrometry for identity confirmation, to ensure it meets stringent research-grade specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. Due to its hygroscopic nature, allow the vial to equilibrate to room temperature before opening to minimize moisture uptake. For long-term storage, consider storing under an inert atmosphere.
