General description

聚(乙二醇)(PEG)是一种非离子型亲水聚合物,并且可以以不同的分子量获得。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,这对于生物材料的纯化来说是必需的。 PEG还可与细胞膜相互作用,从而促进细胞融合。
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. Polyethylene glycol (PEG) is an eco-friendly, biodegradable polymer widely used in pharmaceuticals and cosmetics. Its non-toxic nature and versatility make it a sustainable choice, derived from renewable resources, contributing to greener product formulations. Click here for more information.

Application

聚乙二醇已被用于开发一种利用质粒DNA有效转化乳铁短杆菌原生质体的方法。它已被用作可使脾细胞与骨髓瘤细胞系SP2/0发生融合的融合剂。
