The endotoxin content of a sample containing polysaccharide e.g. PSA and endotoxin is reduced by passing the sample through an affinity chromatography column to which endotoxin adsorbs, whereby polysaccharide passes through the column and is collected to provide a product solution of polysaccharide e.g. PSA having reduced endotoxin content. A multistep process can be used and columns used comprise a polymixin B gel, Detoxi-Gel, Cellufine, EndoTrap Red or EndoTrap Blue. |
