HIGH MOLECULAR COMPOUND COMPRISING UNIT OF ASIALOGLYCOPROTEIN ACCEPTOR-DIRECTING COMPOUND AND UNIT OF CHELATE-FORMING COMPOUND CHEMICALLY BONDED THERETO, AND ITS UTILIZATION

摘要

A high molecular compound useful as a non-radioactive carrier, which comprises at least one unit of (1) an asialoglycoprotein acceptor-directing compound and at least one unit of (2) a chelate-forming compound chemically bonded thereto, and which may be labeled with a radioactive metallic element to give a radioactive metallic element-labeled product useful as a radioactive diagnostic or therapeutic agent for liver.
