The attractive properties of avidin (streptavidin) and biotin, in particular their strong affinities (Kd = 10(-15)M), may be used to advantage in imaging applications. These molecules have been used in this preliminary investigation to improve the targeting of 111In in

A simple and efficient method of covalently coupling the strong chelator diethylenetriaminepentaacetic acid to proteins was developed for radiolabeling immunoglobulin G antibodies. After being coupled and labeled with indium-111, a monoclonal antibody to carcinoembryonic antigen retained its ability to bind
