一般描述
该产品是从大肠杆菌血清型 O26:B6中提取的，并已通过凝胶过滤进行纯化。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血清型已经以1 μg/ml用于刺激中性粒细胞。
应用
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，并且暴露在无包膜菌株的细胞表面。它们有助于维持外层膜的完整性，并保护细胞免受胆汁盐和亲脂性抗生素的破坏。
制备说明
本品溶于水(5 mg/ml)或细胞培养基（1 mg/ml），得到浑浊的淡黄色溶液。以盐水为溶剂时，经过涡旋并加热至70-80 oC后，得到浓度更高但仍然浑浊的溶液（20 mg/ml）。脂多糖分子可在各种溶剂中形成胶束。在水和磷酸盐缓冲盐水中，可观察到混浊的溶液。使用有机溶剂不会得到更澄清的溶液。以甲醇为溶剂将得到含漂浮物的混浊悬浮液，而以水为溶剂将得到均匀的混浊溶液。

We previously established that neutrophil-derived dipeptidyl peptidase I (DPPI) is essential for experimental abdominal aortic aneurysm (AAA) development. Because DPPI activates several neutrophil serine proteases, it remains to be determined whether the AAA-promoting effect of DPPI is mediated by neutrophil
