Azide/azido functionalized polyethylene glycol (N3-PEG-X) is a bifunctional PEG derivative that can be used to modify proteins, peptides and other materials. Azide group can react with alkyne in aqueous solution catalyzed by copper. It can also be reduced into amine group easily while another functional group can be react with other molecules or functional groups. PEGylation can increase solubility and stability and reduce immunogenicity of peptides and proteins. It can also suppress the non-specific binding of charged molecules to the modified surfaces.

乙烯-乙二醇(PEG)链附着在上面。和以上讨论的聚酰胺树脂一样,它试图提高固相载体中肽链的溶剂化。研究过各种链长的PEG,但应用最成功是分子量在2000~3000Da之间的。 近年来用机器合成多肽发展很快。机器合成包括半自动(间歇式)和自动(连续流动)两种形式,它与手工合成相比,具有快速、完全、方便等优点。而由于PEG-PS树脂一般都有较好的物理化学特性,如溶胀性,物理稳定性,在流动系统中抗磨和抗机械压力能力等,因而,它也随之发展起来。如Kate SA,McGuinners BF 等最近报道该实验室研究的“低
