一般說明
本产品是从大肠杆菌血清型 O55：B5 中提取而来，并通过离子交换进行了纯化。源菌株是 CDC 1644-70。LPS O55：B5 已用于刺激人腹膜巨噬细胞，以 1 ng/mL 的浓度，并以 1-100 ng/mL 的浓度刺激马腹膜巨噬细胞。
應用
脂多糖（LPS）是革兰氏阴性细菌细胞壁的特征组分。脂多糖及其脂质 A 部分通过 Toll 样受体 4（TLR4）刺激先天免疫系统的细胞，Toll 样受体 4是 Toll 样受体蛋白家族的成员，其识别常见的病原体相关分子模式（PAMP）。
生化／生理作用
脂多糖（LPS）位于膜的外层，并且在非包膜菌株中暴露在细胞表面上。它们有助于外膜的完整性，并保护细胞免受胆汁盐和亲脂性抗生素的影响。
準備報告
产物可溶于水（5mg/ml）或细胞培养基（1mg/ml），产生模糊的淡黄色溶液。在涡旋，并升温至 70-80 oC 后，在含水盐水中得到更浓缩但仍然浑浊的溶液（20 mg/ml）。脂多糖是在每种溶剂中形成胶束的分子。在水和磷酸盐缓冲盐水中观察到浑浊的溶液。有机溶剂不能提供更澄清的溶液。甲醇产生具有漂浮物的浑浊悬浮液，而水产生均匀浑浊溶液。
