Quality Control

Our Tyrosyl-Glutamyl-Tyrosyl-Glutamic Acid is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, MS for identity confirmation, and chiral analysis. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment to ensure traceability and compliance with your research or development requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent degradation from atmospheric moisture. For long-term storage, consider desiccants or inert atmosphere.
