English name: LPS; Lipopolysaccharides from Escherichia coli 055: B5

Grade: BR

Purified by: phenol extraction

Total imports:<3% Protein (Lowry)

Protein by body: ＜ 3.0%

Solution: Clear to have colors to light yellow green solution at 5mg/ml in water

Character: White to yellowish brown powder

Purpose: Biochemical research. Can be used as a complex of lipids and polysaccharides; As the main component of the cell wall of Gram negative bacteria, lipopolysaccharides are endotoxins and important group specific antigens (O antigens). Lipopolysaccharides are composed of three parts. Lipid A is a glycolipid that constitutes endotoxin activity and is covalently linked to heteropolysaccharide chains. It has two parts: one is the core polysaccharide, which is constant within the relevant strain; Another O-specific chain is highly variable. The lipopolysaccharide of Escherichia coli is a commonly used B cell mitogenic factor, also known as polyclonal activator, in laboratory immunology
