Quality Control

Our γglu-L-Cys-γglu-L-Cys-Gly-Oh is produced 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 heavy metals, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C for long-term stability. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under desiccant or inert atmosphere after opening to prevent degradation.
