Quality Control

Our H-Lys-Arg-Asn-Lys-Asn-Asn-Ile-Ala-Oh 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 the high standards required for research applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting purity, assay, and other critical parameters.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This hygroscopic (moisture-sensitive) material should be allowed to equilibrate to room temperature in a desiccator before opening to prevent condensation and hydrolysis. For short-term use, store at 2-8°C.
