一般說明
该产品是来自大肠杆菌血清型 O26：B6的酚提取物。源菌株是ATCC 12795。来自血清型 026的LPS：B6是来自大肠杆菌的唯一 LPS，其在SDS-PAGE 上表现出短链长行为。该 LPS的短链长度接近突变粗糙株 LPS的短链长。该 LPS 血清型（1ug/ml），用于刺激中性粒细胞。
應用
脂多糖（LPS）是革兰氏阴性细菌细胞壁的特征成分。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，TLR4是Toll样受体蛋白家族的成员，该家族可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，在非包封的菌株中，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），产生浑浊的、淡黄色溶液。在经过涡旋和加温至 70-80oC 后，在水溶的盐水中得到更浓缩、但仍然浑浊的溶液（20mg/ml）。脂多糖是在各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混浊悬浮液，而水产生均匀混浊的溶液。
