A nucleic acid complex for delivering a nucleic acid or a derivative thereof to a cell comprises the components: A. a nucleic acid or a derivative thereof; B. a cationic polymer; and C. a preformed polyethylene glycol-cationic polymer copolymer. The complex has a conformation in which the nucleic acid or derivative thereof is condensed and wherein component C is bound to component A such that the poylethylene glycol groups of component C are located at the surface of the complex. The complexes which are stable to aggregation are useful for the delivery of nucleic acids or derivatives thereof to cells in biological systems.

Abstract

A nucleic acid complex for delivering a nucleic acid or a derivative thereof to a cell comprises the components: A. a nucleic acid or a derivative thereof; B. a cationic polymer; and C. a preformed polyethylene glycol-cationic polymer copolymer. The complex has a conformation in which the nucleic acid or derivative thereof is condensed and wherein component C is bound to component A such that the poylethylene glycol groups of component C are located at the surface of the complex. The complexes which are stable to aggregation are useful for the delivery of nucleic acids or derivatives thereof to cells in biological systems.
