Hochmolekulare Verbindung, bestehend aus einer Einheit einer zum Asialoglykoproteinakzeptor leitenden Verbindung und aus einer Einheit einer chelatformenden, an dieser chemisch gebundenen, Verbindung, und ihre Verwendung.

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.
