Quality Control

Our Capsular Polysaccharide K98 is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing including identity confirmation, purity assessment, and impurity profiling to ensure it meets the stringent requirements for biomedical research and pharmaceutical applications. Certificates of Analysis (COA) detailing specifications such as polysaccharide content, protein/nucleic acid limits, and endotoxin levels are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store desiccated at -20°C or below. This material is hygroscopic (moisture-sensitive). Allow the sealed vial to equilibrate to room temperature before opening to prevent condensation.
