一般描述
本品为从鼠伤寒沙门氏菌中提取的 TCA。来源菌株为 ATCC 7823。该 LPS 血清型已被用于诱导大鼠和豚鼠的 NOS。
应用
脂多糖（LPS）是革兰氏阴性细菌细胞壁的特征组分。LPS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。
制备说明
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。

The costs of developing, maintaining, and activating the immune system have been cited as an important force shaping life-history evolution in animals. Immunological defenses require energy, nutrients and time that might otherwise be devoted to other life-history traits like sexual
