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).

In vitro, endotoxin causes a variety of problems in cell-based research. In vivo, endotoxin may cause various […]
