Purpose: research, experiments can be used for complex lipids and polysaccharides; as a major component of the cell wall of Gram-negative bacteria, lipopolysaccharide endotoxin and important group-specific antigen (O antigen ) lipopolysaccharide consists of three parts. .. lipid a (Lipid A) constituting the endotoxin activity of lipid, covalently coupled to the heteropolysaccharide chain, has two parts : First, the core polysaccharide, in the relevant strain is a constant; another O -specific chain (O-specific chain) is highly variable. Escherichia coli lipopolysaccharide immunology laboratory is a common B cell mitogenic factor that is a polyclonal activating factor (polyclonal activator)
