Quality Control

Our H-Lys-Leu-Lys-Oh is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis, and identity confirmation, to ensure it meets rigorous research and pharmaceutical-grade standards. Certificates of Analysis (COA) with detailed specifications are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept sealed in a dry environment to prevent moisture absorption, which can affect stability and purity. For long-term storage, consider desiccants or inert atmosphere.
