一般說明

本品为肠炎沙门菌中提取的苯酚。来源菌株为 ATCC 13076。肠炎沙门氏菌的脂多糖在小鼠脾细胞中具有致突变性,并在这些细胞中引起空斑形成反应。

應用

脂多糖 (LPS) 是革兰氏阴性菌细胞壁的特征性成分。LPS 及其脂质 A 部分通过 Toll 样受体 4 (TLR4) 刺激天然免疫系统的细胞。

生化/生理作用

脂多糖(LPS)位于膜的外层,并且在非包封的菌株中,其暴露于细胞表面。它们有助于外膜的完整性,并可保护细胞免受胆汁盐和亲脂性抗生素的作用。

準備報告

该产品可溶于水(5mg / ml)或细胞培养基(1mg / ml),产生浑浊的淡黄色溶液。当涡旋并升温至70-80 oC后,在盐水中可获得更高浓度的溶液(20mg/ml),但仍然是浑浊的溶液。脂多糖是一种在各种溶剂中都形成胶束的分子。在水和磷酸盐缓冲盐水中可观察到浑浊的溶液。有机溶剂无法使溶液变澄清。甲醇会产生含有漂浮物的混浊悬浮液,而水会产生均匀的混浊溶液。
