The present invention provides a method for targeting a gene delivery vehicle to a selected cell type in a warm-blooded animal, comprising the step of administering to a warm-blooded animal a targeting element coupled to a first high affinity molecule of a high affinity binding pair, the coupled targeting element being capable of specifically binding to a selected cell type in the warm-blooded animal, and administering to the animal a gene delivery vehicle coupled to a second high affinity molecule of the high affinity binding pair, the second high affinity molecule being capable of specifically binding to the first high affinity molecule, such that the gene delivery vehicle is targeted to the selected cell type upon administration. |
