General description

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。
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)已用于Galegae orientalis幼苗的胁迫(脱水)处理。它已被用于制备水性两相系统以研究跨界面的蛋白质扩散。

Other Notes

蛋白质的分级沉淀;原生质体融合;病毒纯化;在含有PEG和抗体的琼脂糖凝胶上进行蛋白电印迹

Mechanical stability of epithelia requires firm attachment to the basement membrane via hemidesmosomes. Dysfunction of hemidesmosomal proteins causes severe skin-blistering diseases. Two plakins, plectin and BP230 (BPAG1e), link the integrin α6β4 to intermediate filaments in epidermal hemidesmosomes. Here, we show
