Quality Control

Our Smb Protein is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including purity assessment by HPLC, biological activity assays, and endotoxin level checks, to ensure it meets the high standards required for research and in-vitro diagnostic use. Certificates of Analysis (COA) detailing purity, activity, and specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C for long-term stability. This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent moisture absorption. For extended storage, consider aliquoting and freezing at -20°C or below under inert atmosphere.
