概述
聚乙二醇(PEG)是非离子型亲水聚合物，有不同的分子量可供选择。它有助于蛋白和核酸的纯化和晶体生长。PEG和葡聚糖一起产生生物材料纯化所需的聚合物双水相体系。PEG还可与细胞膜相互作用，从而促进细胞融合。
应用
聚乙二醇（PEG）用于确定 NADPH 氧化酶 4（Nox4）在调控血管内皮生长因子（VEGF）表达中的信号传导作用。在物种特异性定量聚合酶链反应（qPCR）中稀释裂解液。
Poly(ethylene glycol) (PEG) is a non-ionic hydrophilic polymer and is available in different molecular weights. It helps in the purification and crystal growth of proteins and nucleic acids. PEG and dextran together result in aqueous polymer two phase system, which is required for the purification of biological materials. PEG also interacts with cell membrane, thereby allowing cell fusion.
Application
