Abstract
The present invention concerns a novel composition comprising a nucleic acid; and a chitosan containing branching groups covalently linked to the amino groups wherein said branches are selected from the following groups; alkyl with 2 or more carbon atoms, monosaccharides, oligosaccharides or polysaccharides. The composition is particularly useful as a non-viral gene delivery system. The composition facilitates the introduction of the nucleic acid into the cells to which it is administrated, as well as the expression of the function of the nucleic acid.
