Quality Control

Our Cys-Gln-Asp-Ser-Glu-Thr-Arg-Thr-Phe-Tyr is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and MS for identity confirmation, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing all specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This product is hygroscopic (moisture-sensitive) and should be handled under dry, inert conditions to prevent degradation. Allow the vial to equilibrate to room temperature in a desiccator before opening to minimize moisture uptake.
