Synonyms: LPS, from Escherichia coli (O55:B5)
Lipopolysaccharides, from E. coli O55:B5 (LPS, from Escherichia coli (O55:B5)) are endotoxins and TLR4 activators extracted from Escherichia coli (E. coli O55:B5) and are classified as S (smooth) type LPS. Lipopolysaccharides, from E. coli O55:B5 possess the typical three-part structure: O-antigen, core oligosaccharide, and lipid A. Lipopolysaccharides, from E. coli O55:B5 activate TLR-4 in immune cells, exhibit high pyrogenicity, and demonstrate dose and serotype specificity. Lipopolysaccharides, from E. coli O55:B5 can be widely 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.

Lolamicin is an orally effective inhibitor that specifically targets the Gram-negative bacteria lipoprotein transport system LolCDE complex. It selectively inhibits the transmembrane transport of outer membrane lipoproteins by competitively binding to lipoprotein binding sites. Lolamicin destroys the integrity of the bacterial outer membrane, leading to cell death, and has both bactericidal and antibacterial activity. It has significant effects on multidrug-resistant Enterobacteriaceae pathogens (such as Escherichia coli and Klebsiella pneumoniae). Lolamicin can be used to inhibit the study of acute pneumonia, sepsis and other infections caused by Gram-negative bacteria .
