Quality Control

Our Fimbrial Antigen F165(2) is manufactured under stringent conditions to ensure batch-to-batch consistency and high biological activity. Each lot undergoes rigorous purity analysis, identity confirmation, and functional testing. A comprehensive Certificate of Analysis (COA) detailing purity, protein concentration, endotoxin levels, and identity is provided with every shipment to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store lyophilized material at -20°C or below. Reconstituted aliquots should be stored at -70°C or lower and avoid repeated freeze-thaw cycles. The product is hygroscopic (moisture-sensitive); ensure containers are sealed tightly after use.
