概述

​该产品是从大肠杆菌血清型O55:B5中通过TCA提取获得。源菌株为CDC 1644-70。LPS O55:B5已用于以1ng/ml的浓度刺激人腹膜巨噬细胞,以及以1-100ng/ml的浓度刺激马腹膜巨噬细胞。 

使用方法: 

该产品可溶于水(5mg/mL)或细胞培养基(1mg/mL),并产生浑浊的淡黄色溶液。 脂多糖是一种能在各种溶剂中形成胶束的分子。在水和磷酸盐缓冲盐水中可观察到浑浊的溶液。通过有机溶剂无法获得更澄清的溶液。在甲醇会产生含有漂浮物的混浊悬浮液,而在水中则产生均匀的浑浊溶液。 

应用: 

脂多糖(LPS)是革兰氏阴性细菌细胞壁的特征组分。脂多糖及其脂质 A 部分通过 Toll 样受体 4(TLR4)刺激先天免疫系统的细胞,Toll 样受体 4是 Toll 样受体蛋白家族的成员,其识别常见的病原体相关分子模式(PAMP) 

Lipopolysaccharide,|E. coli|O55:B5 is a component of the cell wall of the O55:B5 serotype of the Gram-negative bacteria,|Escherichia coli|. Lipopolysaccharides (LPS) are made up of a hydrophobic lipid, a hydrophilic core polysaccharide chain and a hydrophilic O-antigenic polysaccharide side chain. LPS molecules contribute to the outer integrity of the cell membrane, protect the cell against bile salts and lipophilic antibiotics, and act as endotoxins in animals. LPS induces a strong immune response by binding to the CD14/TLR4/MD2 receptor complex, which promotes the secretion of pro-inflammatory cytokines. LPS is also an exogenous pyrogen. LPS O55:B5 has been derived from a serotype of|E. coli|O55:B5, which is part of a subdivision based on the O antigen component of LPS. Lipopolysaccharide, E. coli O55:B5 is a form of lipopolysaccharide (LPS) extracted from wild-type S-form E. coli serotype O55:B5. Lipopolysaccharide, E. coli O55:B5 is commonly used to activate toll-like receptor 4 (TLR4) on leukocytes, eliciting inflammatory signaling in isolated cells and in vivo.1,2,3,4 Lipopolysaccharide, E. coli O55:B5 includes three regions, the O-antigenic polysaccharide chain, the core oligosaccharide, and lipid A. Lipopolysaccharide, E. coli O55:B5 stimulates the activity of inducible nitric oxide synthase. Lipopolysaccharide, E. coli O55:B5 induces apoptosis in mouse thymus and swine lymphocytes. Lipopolysaccharide, E. coli O55:B5 is also known as LPS. Lipopolysaccharide, E. coli O55:B5is a component of the cell wall of Gram-negative bacteria and Specific activator of Toll-like receptor (TLR) 4.

Usage:

The product is soluble in water (5 mg/ml) or cell culture medium (1 mg/ml) yielding a hazy, faint yellow solution. A more concentrated, though still hazy, solution (20 mg/ml) has been achieved in aqueous saline after vortexing and warming to 70-80 oC. Lipopolysaccharides are molecules that form micelles in every solvent. Hazy solutions are observed in water and phosphate buffered saline. Organic solvents do not give clearer solutions. Methanol yields a turbid suspension with floaters, while water yields a homogeneously hazy solution.
