发明名称 Method for endotoxin removal
摘要 The present invention relates to a method for endotoxin removal from a sample comprising the following steps: combining the sample comprising one or more target molecule(s) with a chromatography media comprising beads having an inner porous core functionalized with ligands capable of binding endotoxin and an outer porous layer without functional groups and a pore size small enough to exclude the target molecule from the inner core; and collecting the sample from the media, wherein the sample comprises an endotoxin level which is at least 75% less, preferably 90% less, than before the removal and the yield of the target molecule is at least 75%.

主权项 1. A method for endotoxin removal from a sample comprising the following steps: combining the sample comprising one or more target molecule(s) and an endotoxin with a chromatography media comprising beads having an inner porous core functionalized with ligands capable of binding the endotoxin and a 5-7 μm thick outer porous layer without functional groups and a pore size small enough to exclude the target molecule from the inner core, wherein the exclusion limit of said outer porous layer is about 700 kDa; and collecting the sample from the media, wherein the sample comprises an endotoxin level which is at least 75% less, preferably 90% less, than before the removal and the yield of the target molecule is at least 75%.
