一般描述

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。

应用

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。

制备说明

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。
