Lipopolysaccharides, from E. coli O111:B4 (LPS, from Escherichia coli (O111:B4)) are endotoxins and TLR4 activators extracted from Escherichia coli (E. coli O111:B4) and are classified as S (smooth) type LPS. Lipopolysaccharides (LPS), from E. coli O111:B4 possess the typical three-part structure: O-antigen, R3-type core oligosaccharide, and lipid A. Lipopolysaccharides (LPS), from E. coli O111:B4 activate TLR-4 in immune cells and can cause significant gastric diseases. Lipopolysaccharides (LPS), from E. coli O111:B4 can be used to induce cellular inflammation and establish animal models related to inflammation.
It is recommended to prepare a solution with concentration ≥2 mg/mL. Vortex thoroughly for more than 10 minutes. Due to the adsorption characteristics of LPS, silanized container or low adsorption centrifuge tubes should be used for aliquoting and storage, and mix thoroughly before use.
