1. A kit containing reagents for use in preparing a therapeutic liposome composition sensitized to a target cell, comprisinga liposomal composition composed of pre-formed liposomes having an entrapped therapeutic agent;
- anda plurality of conjugates, each conjugate composed of (i) a lipid having a polar head group and a hydrophobic tail, (ii) a hydrophilic polymer having a proximal end and a distal end, said polymer attached at its proximal end to the head group of the lipid, and (iii) a targeting ligand attached to the distal end of the polymer;
wherein a therapeutic, target-cell sensitized liposome composition is formed by incubating the liposomal composition with a selected conjugate.

Abstract
Reagents for use in preparing a therapeutic liposome composition sensitized to a target cell are described. The reagents include a liposomal composition composed of pre-formed liposomes having an entrapped therapeutic agent and a plurality of targeting conjugates composed of a lipid, a hydrophilic polymer and a targeting ligand. The therapeutic, target-cell sensitized liposome composition is formed by incubating the liposomal composition with a selected conjugate.
