概述
聚乙二醇 (PEG) 是一种非离子型亲水性聚合物，具有不同的分子量。有助于蛋白质和核酸的纯化和晶体生长。PEG 与葡聚糖形成聚合物双水相系统，是生物材料净化所必需的。PEG 还与细胞膜相互作用，从而使细胞融合。
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
Poly(ethylene glycol) has been used in the transformation mix solution of yeast. It has been used to prepare an agar-solute substrate to study the influence of cocoon of Cyclorana australis on liquid water exchange with the substrate.
Other Notes
In protein crystallization; As fusogen to obtain hybridomas for monoclonal antibody production; Significantly enhances the transfer of membrane immunoblotting
