Endotoxin is the lipopolysaccharide (LPS) complex located in the outer membrane of gram-negative bacteria. A single E.coli bacterium contains ~2 million LPS molecules (2 - 20 fg/cell). During experimental procedures, large amount of endotoxins are shed and can easily contaminate labware, buffers and downstream products. In vitro, endotoxin causes a variety of problems in cell-based research. In vivo, endotoxin may cause various side effects, including inflammatory response, organ failure or septic shock in host organisms. Therefore, it is critical to remove endotoxin from samples and products. BioVision`s ToxOutTM High Capacity Endotoxin Removal Agarose can effectively eliminate high concentration endotoxin to < 0.05 EU/ml in solutions cont
