The invention provides gene transfer compositions using as the gene carrier a biodegradable polymer that contains one or more cationic alpha amino acids, such as arginine or agmatine. The compositions form a tight soluble complex with a poly nucleic acid suitable for transfecting target cells to effect translation of the cargo poly nucleic acid by the target cell. Thus, such compounds are useful both in vitro and in vivo.
本发明提供了一种
基因转移组合物,其中使用可
生物降解的聚合物作为
基因载体,该聚合物含有一种或多种阳离子α
氨基酸,例如精
氨酸或
脲甲酸。该组合物与适用于转染目标细胞的聚核酸形成紧密的可溶性复合物,以通过目标细胞转化载荷聚核酸的翻译。因此,这些化合物在体外和体内都有用。
