Quality Control

Our Tyrosyl-Phenylalanyl-Arginyl-Lysyl-Aspartic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, MS for identity confirmation, and tests for residual solvents and moisture content. We provide Certificates of Analysis (COA) with each shipment, detailing all specifications and test results to ensure compliance with your research and development requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry, cool place. This material is hygroscopic (moisture-sensitive). For long-term storage, desiccate and keep under inert atmosphere. Allow the sealed container to reach room temperature before opening to prevent moisture condensation.
