国际上推出了一些阳离子聚合物基因转染技术,以其适用宿主范围广,操作简便,对细胞毒性小,转染效率高受到研究者们的青睐。其中树枝状聚合物(Dendrimers)和Polysciences聚乙烯亚胺(PolyethyleniminePEI)的转染性能最佳,但树枝状聚合物的结构不易于进一步改性,且其合成工艺复杂。Polysciences聚乙烯亚胺是一种具有较高的阳离子电荷密度的有机大分子,每相隔二个碳个原子,即每“第三个原子都是质子化的氨基氮原子,使得聚合物网络在任何pH下都能充当有效的“质子海绵”(protonsponge)体。这种聚阳离子能将各种报告基因转入各种种属细胞,其效果好于脂质聚酰胺,经进一步的改性后,其转染性能好于树枝状聚合物,而且它的细胞毒性低。大量实验证明,PEI是非常有希望的基因治疗载体。目前在设计更复杂的基因载体时,PEI经常做为核心组成成分。
