一般描述
本品从大肠杆菌血清型K235中提取，经凝胶过滤纯化。来源菌株为 ATCC 13027。
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作用。
制备说明
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，并升温至 70-80oC 后，含水盐水变得更浓缩，但仍然浑浊（20mg/ml）。脂多糖分子在每种溶剂中均形成胶束。在水和磷酸盐缓冲盐水中观察到浑浊的溶液。使用有机溶剂，溶液也是浑浊的。甲醇产生具有漂浮物的浑浊悬浮液，而水则产生均匀浑浊的溶液。

The adenoviral protein E1A has been proposed to play a role in the pathophysiology of COPD, in particular by increasing IL-8 gene transcription of lung epithelial cells in response to cigarette smoke-constituents such as LPS. As IL-8 production is also

Perforin-2 (MPEG1) is thought to enable the killing of invading microbes engulfed by macrophages and other phagocytes, forming pores in their membranes. Loss of perforin-2 renders individual phagocytes and whole organisms significantly more susceptible to bacterial pathogens. Here, we reveal
