Quality Control

Our Poly-L-Serine is manufactured under a quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing specifications such as assay, molecular weight distribution, and residual solvents is provided with every shipment. We support compliance with relevant industry standards for research and development 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) and must be kept in a desiccated environment to prevent degradation. For long-term stability, consider storage under inert atmosphere.
