Quality Control

Our L-Cys-Gly-L-Asn-L-Leu-L-Ser-L-Thr-L-Cys-L-Met-L-Leu-Gly-L-Thr-L-Thr-L-Thr-L-Gln-L-Asp-L-Phe-L-Asn-L-Lys-L-Phe-L-His-L-Thr-L-Phe-L-Pro-L-Gln-L-Thr-L-Ala-L-Ile-Gly-L-Val-Gly-L-Ala-L-Pro-NH2 is manufactured under strict quality systems. Each batch undergoes rigorous analytical testing including HPLC for purity, MS for identity confirmation, and amino acid analysis to ensure sequence integrity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment, supporting compliance with research and development standards.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a freezer. For long-term storage, consider lyophilized (freeze-dried) form under inert atmosphere. The product is hygroscopic (moisture-sensitive); allow the sealed vial to equilibrate to room temperature before opening to prevent condensation and moisture uptake. Store away from strong acids and oxidizing agents.
