产品说明
一般描述
Lipopolysaccharide (LPS), also known as endotoxin, is present mainly in the cell wall of Gram-negative bacteria. It comprises three structural regions the O-side chain, a middle polysaccharide component, and Lipid A which contributes to the pyrogenic nature of LPS.
应用
LPS, E. Coli O111:B4 has been used for priming macrophages to upregulate genes necessary for NOD-, LRR- and pyrin domain-containing protein 3 (NLRP3) inflammasome activation. It has also been used to stimulate Raw264.7 cells before pull-down assay.
生化/生理作用
Lipopolysaccharide (LPS), an effective immunostimulant induces inflammatory and immune responses by activating Toll-Like Receptor 4 (TLR4). It also contributes to osteoclastogenesis in mice. LPS serves as a permeability barrier around the cell surface to restrict the entry of toxic molecules such as antibiotics and bile salts. It acts as a pyrogenic agent and eventually induces septic shock in host cells.
