Quality Control

Our Val-Gly-Ser-Glu is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity, mass spectrometry (MS) for identity confirmation, and amino acid analysis (AAA). Certificates of Analysis (COA) detailing all specifications and test results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to minimize exposure to atmospheric humidity. For long-term storage, consider desiccants or inert atmosphere.
