一般說明
本品为从粘质沙雷氏菌中提取的苯酚。源菌株是ATCC 21639。
生化／生理作用
脂多糖（LPS）位于膜的外层，并且暴露在无包膜菌株的细胞表面。它们有助于维持外层膜的完整性，并保护细胞免受胆汁盐和亲脂性抗生素的破坏。
準備報告
本品溶于水(5 mg/ml)或细胞培养基（1 mg/ml），得到浑浊的淡黄色溶液。以盐水为溶剂时，经过涡旋并加热至70-80 oC后，得到浓度更高但仍然浑浊的溶液（20 mg/ml）。脂多糖分子可在各种溶剂中形成胶束。在水和磷酸盐缓冲盐水中，可观察到混浊的溶液。使用有机溶剂不会得到更澄清的溶液。以甲醇为溶剂将得到含漂浮物的混浊悬浮液，而以水为溶剂将得到均匀的混浊溶液。

Gram-negative bacterial infections are accompanied by inflammation and somatic or visceral pain. These symptoms are generally attributed to sensitization of nociceptors by inflammatory mediators released by immune cells. Nociceptor sensitization during inflammation occurs through activation of the Toll-like receptor 4
