Solubility：Clear to hazy colorless to light yellow-green solution at 5mg/ml in water

Physicochemical properties: off white to yellowish brown powder

Purpose: biochemical research. It can be used as a complex of lipids and polysaccharides; As the main component of the cell wall of Gram-negative bacteria, lipopolysaccharide is endotoxin and an important group specific antigen (O antigen). Lipopolysaccharide is composed of three parts. Lipid A (lipid A) is a glycolipid that constitutes endotoxin activity and is covalently linked to the heteropolysaccharide chain. It has two parts: one is the core polysaccharide, which is constant in the relevant strains; Another O-specific chain is highly variable. Lipopolysaccharide of Escherichia coli is a commonly used B-cell mitogen in laboratory immunology, that is, polyclonal activator
