一般描述

本品为绿脓杆菌血清型10提取的 TCA。来源菌株为 ATCC 27316。

应用

脂多糖 (LPS) 是革兰氏阴性菌细胞壁的特征性成分。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之一，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，其暴露于细胞表面。它们有助于外膜保持完整，并可保护细胞免受胆汁盐和亲脂性抗生素的影响。

制备说明

本品可溶于水（5 mg/mL）或细胞培养基（1 mg/mL），产生淡黄色浑浊溶液。涡旋并加热至 70-80 ^o C 后，在盐水中获得了更浓缩但仍浑浊的溶液（20 mg/mL）。脂多糖是在每种溶剂中形成胶束的分子。在水和磷酸盐缓冲盐水中观察到浑浊溶液。有机溶剂不能提供更清晰的溶液。甲醇产生浑浊、带漂浮物的混悬液，而水产生均匀的浑浊溶液。

Mucosal immunology, 9(4), 1039-1050 (2015-11-12)

Cystic fibrosis (CF) patients battle life-long pulmonary infections with the respiratory pathogen Pseudomonas aeruginosa (PA). An overabundance of mucus in CF airways provides a favorable niche for PA growth. When compared with that of non-CF individuals, mucus of CF airways

Evolutionary conserved mechanisms pervade structure and transcriptional modulation of allograft inflammatory factor-1 from sea anemone Anemonia viridis.

Angela Cuttitta et al.

Fish & shellfish immunology, 67, 86-94 (2017-06-06)

Gene family encoding allograft inflammatory factor-1 (AIF-1) is well conserved among organisms; however, there is limited knowledge in lower organisms. In this study, the first AIF-1 homologue from cnidarians was identified and characterised in the sea anemone Anemonia viridis. The

Nutrients, 7(6), 4851-4861 (2015-06-18)

Recent studies show that brown rice improves glucose intolerance and potentially the risk of diabetes, although the underlying molecular mechanisms remain unclear. One of the phytochemicals found in high concentration in brown rice is γ-oryzanol (Orz), a group of ferulic

Molecular Interactions of Lipopolysaccharide with an Outer Membrane Protein from Pseudomonas aeruginosa Probed by Solution NMR.
