TOYOPEARL NH2-750F: Flow-through Removal of Endotoxin

Endotoxins are remnants of bacterial cell walls that may contaminate drug products and cause an immunogenic response. They are often referred to as “pyrogens” due to their fever-inducing effects. Endotoxins may be found in drug products either due to contamination from host cells used to produce a drug product in a bacterial expression system or due to adventitious bacterial contamination in non-microbial products. Thus, endotoxin clearance is a requirement of downstream processing of biologics, especially those derived from microbial expression systems that contain endogenous host cell endotoxin. In this study, we evaluate the ability of TOYOPEARL NH2-750F for the removal of endotoxins by anion exchange chromatography.
