脂多糖是一种糖脂,由与脂肪酸连接的碳水化合物组成。脂多糖(LPS)是革兰氏阴性菌细胞壁的特征性成分。典型的LPS分子具有脂质A(一种基于葡糖胺的磷脂)、一个相对短的核心寡糖以及一个远端的多糖(O-抗原)。LPS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。它们通过TLR2和TLR4(toll样受体)对宿主细胞进行刺激。这种刺激可导致各种促炎细胞因子的生成,例如TNFα(肿瘤坏死因子)、IL-1(白细胞介素1)和IL-6。 该产品是从大肠杆菌血清型O111:B4中经酚抽提的。来源菌株来自私人保藏。该LPS血清型已用于刺激B细胞并在人肝细胞中诱导NOS( 一氧化氮合酶)。
应用:
来源于大肠杆菌 O111:B4的脂多糖(LPS)已用于:
刺激巨噬细胞;
小鼠 LPS 预处理;
诱导小鼠急性肾损伤;
诱导小鼠急性呼吸窘迫综合征 (ARDS) ,以研究骨髓间充质干细胞 (BMSC) 来源外泌体的抗炎作用;
诱导重症急性呼吸综合征冠状病毒 2 (SARS-CoV-2) 感染小鼠的高炎症状态;
脂多糖(LPS)是革兰氏阴性菌细胞壁的特征组分。LPS及其脂质A部分可通过能够识别常见的病原体相关分子模式(PAMP)的Toll样受体蛋白家族成员Toll样受体4(TLR4)刺激先天性免疫系统细胞。
Lipopolysaccharides are a type of glycolipid composed of carbohydrates linked to fatty acids. Lipopolysaccharides (LPS) are characteristic components of the cell wall of Gram negative bacteria. A typical LPS molecule consists of lipid A (a glucosamine based phospholipid), a relatively short core oligosaccharide, and a distal polysaccharide (O-antigen). LPS contributes to the integrity of the outer membrane and can protect cells from the effects of bile salts and lipophilic antibiotics. They stimulate host cells through TLR2 and TLR4 (toll like receptors). This stimulus can lead to the generation of various pro-inflammatory cytokines, such as TNF α Tumor necrosis factor, IL-1, and IL-6. This product was extracted with phenol from Escherichia coli serotype O111: B4. The source strain comes from private preservation. This LPS serotype has been used to stimulate B cells and induce NOS (nitric oxide synthase) in human liver cells.
Application:
Lipopolysaccharides (LPS) derived from Escherichia coli O111: B4 have been used for:
Stimulate macrophages;
Mouse LPS pretreatment;
Induce acute kidney injury in mice;
Inducing acute respiratory distress syndrome (ARDS) in mice to study the anti-inflammatory effects of extracellular vesicles derived from bone marrow mesenchymal stem cells (BMSCs);
Inducing a high inflammatory state in mice infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2);
Lipopolysaccharides (LPS) are characteristic components of the cell wall of Gram negative bacteria. LPS and its lipid A fraction can stimulate innate immune system cells through Toll like receptor 4 (TLR4), a member of the Toll like receptor protein family that recognizes common pathogen associated molecular patterns (PAMPs).
