Quality Control

Our Poly-L-Lysyltyrosine is produced and tested under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatographic purity assessment and identity confirmation, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) with detailed specifications are 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 (typically 15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider desiccants or inert atmosphere.
