一般描述
本品由沙门氏菌菌种明尼苏达粒径Re 595（Re突变体）采用酚-氯仿-石油醚提取程序制备而成。来源菌株为 ATCC 49284。菌株 Re 595 的 LPS 中的一种独特结构显示可诱导人血小板分泌和聚集。
应用
- Charge and aggregation pattern govern the interaction of plasticins with LPS monolayers mimicking the external leaflet of the outer membrane of Gram-negative bacteria: This study examines how charge and aggregation patterns affect the interaction of plasticins with lipopolysaccharides (LPS) from rough strains like Salmonella enterica serotype Minnesota Re 595. The findings contribute to understanding the molecular interactions involved in microbial resistance mechanisms (Michel et al., 2015).
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，其暴露于细胞表面。它们有助于外膜的完整性，并可保护细胞免受胆汁盐和亲脂性抗生素的作用。
制备说明
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。

Studies have shown that glycosylphosphatidylinositols (GPIs) of Plasmodium falciparum activate macrophages mainly through Toll-like receptor 2 (TLR2)-mediated signalling and to certain extent through TLR4-mediated signalling to induce proinflammatory cytokine production. However, the ability of parasite GPIs to activate dendritic cells
