一般描述

聚乙二醇（PEG）是一种亲水性的聚合物。它可以通过环氧乙烷的阴离子开环聚合而被轻易的合成为不同的分子量和并带有各种端基。当交联成网络时，PEG可具有高的含水量，形成“水凝胶”。水凝胶的形成可通过电离辐射交联PEG或通过PEG大分子单体与反应性链端的共价交联而引发。PEG引其不会触发免疫反应而成为一种适合于生物学应用的材料。

应用

PEG修饰提高了Bst DNA聚合酶的热稳定性和抑制剂抗性：这项研究表明，聚乙二醇(PEG)修饰显着增强了Bst DNA聚合酶的热稳定性和抑制剂抗性，突出了PEG在改善酶性能以用于生物技术应用方面的潜力（Yang等人，2024年）。

基于莱什曼原虫的冻干真核细胞无细胞蛋白质表达系统的开发：在无细胞蛋白质表达系统的冻干过程中加入PEG证明了其在增强生物技术工作流程的稳定性和效率中的作用（Alfaro-Palma等人，2024年）。

关于纳米材料和共轭聚合物中单线态氧的产生在癌症治疗光动力疗法中的综述：这篇综述重点介绍了PEG化纳米材料在光动力疗法中的应用，强调了其在提高生物相容性和癌症治疗疗效中的重要性（Singh等人，2024年）。

Anxiolytic Drug FGIN-1-27 Ameliorates Autoimmunity by Metabolic Reprogramming of Pathogenic Th17 Cells.

Anju Singh et al.

Scientific reports, 10(1), 3766-3766 (2020-03-01)

Th17 cells are critical drivers of autoimmune diseases and immunopathology. There is an unmet need to develop therapies targeting pathogenic Th17 cells for the treatment of autoimmune disorders. Here, we report that anxiolytic FGIN-1-27 inhibits differentiation and pathogenicity of Th17
