一般說明

本品为 0.2 um 过滤水溶液,含 1 mg/mL 来自大肠杆菌血清型 O26:B6 的脂多糖 (LPS)。这种 LPS 血清型已被用于感染性休克研究。

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,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。

準備報告

用于制备溶液的 LPS 经过苯酚提取和凝胶过滤层析纯化。通过苯酚提取制备的脂多糖含有高达 60% 的 RNA 和少于 1% 的蛋白质。随后通过凝胶过滤色谱法进行纯化,可去除苯酚提取的 LPS 中存在的大部分蛋白质,但留下的产物仍含有 10-20% 的核酸。采用离子交换色谱法进一步纯化,得到含 <1% 蛋白质和 <1% RNA 的 LPS 产品。

In response to inflammatory stimulation, dendritic cells (DCs) have a remarkable pattern of differentiation (maturation) that exhibits specific mechanisms to control immunity. Here, we show that in response to Lipopolysaccharides (LPS), several microRNAs (miRNAs) are regulated in human monocyte-derived dendritic
