一般描述
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。
其他说明
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
