Quality Control

Our Cyclo(L-Asn-L-Leu-L-Ser-L-Phe-L-Leu-L-Pro-L-Val-) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets stringent specifications for research and development use. Certificates of Analysis (COA) detailing batch-specific results are provided and available upon request.

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, which can affect stability and handling properties.
