Notes: LPS from Escherichia coli O111:B4 is a form of lipopolysaccharide (LPS) extracted from wild-type S-form E. coli serotype O111:B4. It is commonly used to activate Toll-like receptor 4 (TLR4) on leukocytes, eliciting inflammatory signaling in isolated cells and in vivo.{31332,31333,31331,31334} This form of LPS includes three regions, the O-antigenic polysaccharide chain, the core oligosaccharide, and lipid A.
