Quality Control

Our Pepstatyl, Gly-Lys-Lys- is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, mass spectrometry for identity confirmation, and tests for residual solvents and heavy metals. Certificates of Analysis (COA) documenting full compliance with specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere.
