Quality Control

Our Lysyl-Arginyl-Arginyltryptophyl-Lysyl-Lysine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, mass spectrometry (MS) for identity confirmation, and amino acid analysis (AAA). We provide full traceability and Certificates of Analysis (COA) detailing all specifications to ensure compliance with your research and 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). Due to its hygroscopic nature, the container must be kept sealed in a dry environment to prevent moisture absorption. For long-term storage, consider desiccants or inert atmosphere.
