Lipopolysaccharides (LPS) 是一种特定的内毒素，是革兰氏阴性细菌细胞壁的主要成分之一。Lipopolysaccharides 由三个部分组成：脂质A (Lipid A)，核心寡糖 (core oligosaccharide) 和 O-特异性多糖 (O-specific polysaccharide)。Lipopolysaccharides 是一种强大的免疫刺激剂，能够激活宿主的免疫系统，特别是通过与免疫细胞表面的 Toll 样受体 4 (TLR4) 结合，引发炎症反应。大多数沙门氏菌血清型的 LPS 具有复杂 O-抗原 (OAg) 结构,核心多糖中 OAg 单元数量在 16-100 多个重复之间变化。通过 OAg 调节因子突变改变 OAg 结构，沙门氏菌与上皮细胞的相互作用会发生改变。长 OAg 的菌株中 SPI1-T3SS 效应蛋白的转运及侵入增加。完全缺乏 OAg 的菌株的侵入性增加并表现出更高的粘附性。本产品来源于肠沙门氏菌 (血清型明尼苏达)。Lipopolysaccharides, from S. enterica serotype minnesota 可用于宿主免疫系统激活以及其在炎症和免疫调节中的研究。

生物活性

Lipopolysaccharides (LPS) are specific endotoxins and one of the major components of the cell wall of Gram-negative bacteria. Lipopolysaccharides consist of three parts: lipid A, core oligosaccharide, and O-specific polysaccharide. Lipopolysaccharides are powerful immune stimulants that can activate the host immune system, particularly by binding to Toll-like receptor 4 (TLR4) on the surface of immune cells, triggering an inflammatory response. The LPS of most Salmonella serotypes has a complex O-antigen (OAg) structure, with the number of OAg units in the core polysaccharide varying between 16 and over 100 repeats. Mutations in OAg-regulating factors that alter the OAg structure can change the interaction between Salmonella and epithelial cells. Strains with long OAg have increased SPI1-T3SS effector protein translocation and invasion. Strains completely lacking OAg exhibit increased invasiveness and higher adhesiveness. This product is derived from Salmonella enterica serotype Minnesota. Lipopolysaccharides, from S. enterica serotype minnesota, can be used to study host immune system activation and its role in inflammation and immune regulation[1][2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
