Abstract
A therapeutic composition derived from a pre-activated photoactive compound and a conveyor for destroying tumor or other pathogenic biological contaminants infecting animal body tissues. The conveyor can either be a matrix support or an antibody. The activation of the photoactive compound to produce the pre-activated photoactive compound is carried out by the use of an activating agent. The pre-activated photoactive compound retains its therapeutic activity subsequent to activation. A method for preparing such a therapeutic composition is disclosed. Methods for treating animal body tissue, either outside the body or inside the body, infected with tumors or other pathogenic biological contaminants are disclosed.
