リポポリサッカリド サルモネラ菌 セロタイプ typhimurium由来

リポ多糖（LPS）は、グラム陰性菌の細胞壁の特徴的な成分です。LPSとその脂質A部分は、一般的な病原体関連分子パターン（PAMP）を認識するトール様受容体タンパク質ファミリーのメンバーであるトール様受容体4（TLR4）によって、自然免疫系の細胞を刺激します。

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.

This product is TCA extracted from Salmonella typhimurium. The source strain is ATCC 7823. This LPS serotype has been used to induce NOS in rats and guinea pigs.

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.
