The present invention is a polymer which may be used to produce a physiologically active, substantially non-immunogenic water soluble polyethylene glycol protein conjugate having the same utility as the protein which forms the conjugate, without having the same properties of producing an immunogenic response possessed by the protein which forms this conjugate.
本发明是一种聚合物,可用于制备生理活性、基本无免疫原性、
水溶性的聚
乙二醇蛋白共轭物,其具有与形成共轭物的蛋白质相同的效用,但不具有形成免疫原反应的特性。
