リポポリサッカリド 大腸菌0127:B8由来

This product is extracted from E. coli serotype O127:B8 and purified by gel filtration. The source strain is ATCC 12740. This LPS serotype has been used in the study of septic shock and to induce NOS in murine macrophages and PAF synthesis in rat glomerular masangial cells.

リポポリサッカリド（LPS）は、グラム陰性菌細胞壁の特徴的な構成要素です。LPS及びそのリピドA部分は、一般的な病原体関連分子パターン（PAMP）を認識するToll様受容体タンパク質ファミリーのメンバーであるToll様受容体4（TLR4）により自然免疫系細胞を刺激します。

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.

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.
