Quality Control

Our Lysyl-Valyl-Leucyl-Aspartic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and MS for identity confirmation, to ensure it meets high-purity research-grade standards. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment to guarantee traceability and consistency for your critical research applications.

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 (moisture-sensitive) nature, the container must be kept sealed in a desiccated environment to prevent degradation. For long-term storage, consider freezing at -20°C under inert atmosphere.
