Quality Control

Our Silk-Like Protein Polymer is manufactured under a strict quality management system. Each batch is subjected to rigorous analytical testing to ensure consistency in molecular weight distribution, amino acid composition, purity, and functional performance. Certificates of Analysis (COA) detailing specifications for assay, endotoxin levels, bioburden, and residual solvents are available upon request. Production can adhere to cGMP guidelines for medical-grade applications.

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 material is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent moisture uptake which can affect properties. For long-term storage, consider desiccants or inert atmosphere.
