Quality Control

Our Leucokinin 2 is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity verification and MS for identity confirmation, to ensure it meets the high standards required for research and development. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting purity, peptide content, and other critical parameters.

Storage

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