Lipopolysaccharides, from E. coli O128:B12 (LPS, from Escherichia coli (O128:B12)) are endotoxins and TLR4 activators extracted from Escherichia coli (E. coli O128:B12) and are classified as S (smooth) type LPS. Lipopolysaccharides, from E. coli O128:B12 possess the typical three-part structure: O-antigen, R3-type core oligosaccharide, and lipid A. Lipopolysaccharides, from E. coli O128:B12 activate TLR-4 in immune cells, can be used to construct animal models of neonatal brain inflammation, and may influence preterm birth in neonates . It is recommended to prepare a stock solution of ≥2 mg/mL and ensure that it is fully mixed and dissolved. Due to the adsorption characteristics of LPS, low adsorption centrifuge tubes should be used for aliquoting and storage.
