Abstract
A targetable gene delivery system is provided for introducing foreign genes into mamallian cells. The system employs a soluble targetable DNA complex and utilizes receptor-mediated endocytosis to endow cell specificity. The soluble DNA-carrying complex is formed by non-covalently binding a ligand conjugate with the foreign gene. The conjugate, in turn, is formed by bonding receptor-specific ligands such as asialoglycoproteins to polycations such as polylysine through covalent bonds such as disulfide bonds. The system exhibits a high degree of cell specificity and offers potential for the treatment of inherited genetic disorders.
