    Abstract: The complex has at least one negatively charged nucleic acid bonded to at least one positively charged polymeric conjugate The conjugate containing a polylysine formed from monomers having free NH3+ groups, and having at least 10% of the free NH3+ groups substituted by residues which can be protonated in a weakly acid medium causing destabilization of cell membranes. Optionally, some of the free NH3+ groups can be substituted by a molecule with a recognition signal by a cell membrane receptor. The free NH3+ groups of the said polylysine make up at least 30% of the monomers of the polymeric conjugate. The residue that causes the destabilization of cell membrane in weak acid of quinolines of the formula: where R1 is hydrogen, R2 is —(CH2)n13 CO2—H, X is hydrogen or chlorine and n is an integer from 1 to 10. The signal is a simple oside or a disaccharide or peptide.
