ABSTRACT:
Diagnostic or therapeutic agents are attached to two or more antibody species having non-overlapping patterns of cross-reactivity to increase the relative amount of the active agent(s) delivered to desired target cells compared to non-target cells. The agents may be attached to monoclonal antibodies which bind to cancer cells so that a higher percentage of the active agent(s) localize on the target cells compared to each type of cross-reactive normal tissue.
