Quality Control

Our H-Ser-Phe-Leu-Leu-Arg-Nh2 is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, MS for identity confirmation, and tests for residual solvents and related substances. Certificates of Analysis (COA) documenting purity, identity, and other critical parameters are provided with every shipment to ensure traceability and compliance with your research or cGMP guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. Due to its hygroscopic nature, the container should be allowed to equilibrate to room temperature before opening to minimize moisture uptake. For long-term storage, consider storing under an inert atmosphere.
