一般說明
本品是使用苯酚:氯仿:石油醚从大肠杆菌EH 100（Ra突变株）中提取的。来源菌株由私人提供。
生化／生理作用
脂多糖（LPS）位于无荚膜菌株的膜外层，暴露于细胞表面。它们有助于维持外膜的完整性，并防止胆汁盐和亲脂性抗生素破坏细胞。
準備報告
通过苯酚-氯仿-石油醚萃取进行制备。
本品可溶于水（5 mg/ml）或细胞培养基（1 mg/ml），产生混浊的淡黄色溶液。溶于生理盐水并涡旋和加热至70-80 oC后，可形成浓度更高但仍然混浊的溶液（20 mg/ml）。脂多糖分子可在各种溶剂中形成胶束。溶于水和磷酸盐缓冲盐水时，可观察到浑浊的溶液。使用有机溶剂不能形成更清晰的溶液。使用甲醇可产生具有漂浮物的混浊悬浮液，而溶于水会产生均匀的混浊溶液。

Pyruvate kinase M2 (PKM2) is a key glycolysis enzyme, and its effect on macrophages has not been entirely elucidated. Here, we identified that the PKM2 small-molecule agonist TEPP-46 mediated PKM2 activation by inducing the formation of PKM2 tetramer and promoted

During interaction with APCs, invariant (i) NKT cells are thought to be indirectly activated by TLR4-dependently activated APCs. However, whether TLR4 directly activates iNKT cells is unknown. Therefore, the expression and function of TLR4 in iNKT cells were investigated. Flow

Inflammatory processes play an important role in the pathogenesis of glomerulopathies. Finding novel ways to suppress glomerular inflammation may offer a new way to stop disease progression. However, the molecular mechanisms that initiate and drive inflammation in the glomerulus are

Bromodomain and extraterminal (BET) proteins are essential to pro-inflammatory gene transcription. The BET family proteins, BRD2, BRD3, BRD4, and testis-specific BRDT, couple chromatin remodeling to gene transcription, acting as histone acetyltransferases, scaffolds for transcription complexes, and markers of histone acetylation.
