概述
聚（乙二醇）（PEG）是非离子型亲水聚合物，并且可以获得不同的分子量形式。它有助于蛋白质和核酸的纯化和晶体生长。PEG可与葡聚糖一起产生含水聚合物两相体系，该体系是生物材料纯化所必需的。PEG还能与细胞膜相互作用，从而使得细胞融合。
应用
聚（乙二醇）已用于HIV（人类免疫缺陷病毒）的浓缩。它已被用于研究乳链菌肽CD（圆二色谱）光谱的溶液中。
其他说明
噬菌体和质粒DNA制备 - λ噬菌体的沉淀; DNA片段的分级分离
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 for concentrating HIV (human immunodeficiency virus). It has been used in the solution prepared to study CD (circular dichroism) spectra of nisin.
