Quality Control

Our peptide products are manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and MS for identity confirmation, to ensure they meet the high standards required for research and development. Certificates of Analysis (COA) with detailed chromatographic data are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. For long-term storage, lyophilized powder is recommended. This product is hygroscopic (moisture-sensitive). Allow the vial to reach room temperature in a desiccator before opening to minimize moisture absorption.
