一般描述

本品是从大肠杆菌血清型O111：B4中提取的TCA。来源菌株由私人提供。该LPS血清型已被用于刺激B细胞并诱导人肝细胞的NOS。

应用

脂多糖（LPS）是革兰氏阴性菌细胞壁的特征组分。LPS及其脂质A部分可通过能够识别常见的病原体相关分子模式（PAMP）的Toll样受体蛋白家族成员Toll样受体4（TLR4）刺激先天性免疫系统细胞。

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。

制备说明

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，可观察到浑浊的溶液。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。
