摘要： The present invention concerns a composition comprising complexes of cationic chitosan oligomers derived from the cationic polysaccharide chitosan, wherein said cationic oligomers contain a weight fraction of less than 20% of oligomers with a Degree of Polymerization (DP) 50, and a nucleic acid. These compositions comprising well-defined cationic chitosan oligomers having a certain distribution of chain lengths, and nucleic acid are advantageous to achieve delivery of the nucleic acid into cells of a selected tissue, and to obtain in vivo expression of the desired molecules encoded for by the nucleic acid.

摘要： 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.
