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。它可促进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)已用于溶解JC-124——一种核苷酸结合结构域富亮氨酸家族热蛋白3基因(NLRP3)炎性小体抑制剂和CoQ10——一种线粒体辅酶Q4。

Poly(ethylene glycol) (PEG) is a non-ionic hydrophilic polymer and is available in different molecular weights. It facilitates 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
Poly(ethylene glycol) (PEG) has been used to dissolve JC-124, nucleotide-binding domain, leucine rich family pyrin containing 3 gene (NLRP3) inflammasome inhibitor and solubilize CoQ10, a mitochondrial coenzyme Q4.
