半岛bd体育手机客户端 说明

一般描述

This product is extracted from E. coli serotype O128:B12 and purified by gel filtration. The source strain is CDC 2440-69.

包装

5, 10 mg in glass bottle

应用

脂多糖(LPS)是革兰氏阴性菌细胞壁的特征性成分。LPS及其脂质A部分可通过Toll样受体4(TLR4)刺激先天免疫系统细胞，TLR4是Toll样受体蛋白家族的成员，它能识别常见的病原体相关分子模式(PAMP)。

生化/生理作用

Lipopolysaccharides (LPS) are localized in the outer layer of the membrane and are, in noncapsulated strains, exposed on the cell surface. They contribute to the integrity of the outer membrane, and protect the cell against the action of bile salts and lipophilic antibiotics.

制备说明

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.
