Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with relevant standards for research and industrial use. Each lot is characterized for purity, identity, and absence of common contaminants such as DNase and protease activity. A Certificate of Analysis (COA) detailing specific test results is 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 2-8°C. This material is hygroscopic (moisture-sensitive) and light-sensitive (store away from light). For long-term stability, consider storage under desiccant or inert atmosphere.
