Quality Control

Our Cyclo(Valyl-Valyl-Tryptophyl-Glutamyl-Alanyl) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via mass spectrometry (MS) and infrared spectroscopy (IR). Certificates of Analysis (COA) detailing all specifications are available upon request to ensure compliance with your research and development requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a desiccated environment to maintain stability and purity.
