Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with research-grade standards. Each lot is characterized for critical parameters including amino acid composition, molecular weight distribution, and purity. Certificates of Analysis (COA) detailing these specifications are available upon request to support your quality assurance protocols.

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 nature, the container should be kept in a desiccated environment to prevent moisture uptake, which can affect stability and handling properties.
