THERAPEUTIC AGENT FOR URINARY BLADDER CANCER

摘要

PROBLEM TO BE SOLVED: To provide a therapeutic agent for urinary bladder cancer which is a titanium oxide-antibody complex imparted with a selective binding ability without losing dispersibility and catalytic activity by modifying an antibody through a linker molecule binding a water-soluble polymer to a titanium oxide complex dispersed in an aqueous solvent with the water-soluble polymer without deteriorating the water-soluble polymer. SOLUTION: The therapeutic agent for the urinary bladder cancer includes: the titanium oxide complex having the water-soluble polymer bound through at least one functional group selected from the group consisting of carboxy, amino, diol, salicylic acid, and phosphoric acid to the surface of titanium oxide particles; the linker molecule bound to the surface thereof; and the antibody bound through the linker molecule.
