<p>A selectively targeted agent comprising a dermatan sulfate having more than about 25 % repeating L-iduronic acid-⊃4,6-di-O-sulfated N-acetyl-D-galactosamine disaccharide units that is covalently attached or bonded to a radioactive metal-ion binding moiety. The targeted agent is useful in preparing radiagnostic and/or radiopharmaceutical agents for diagnostic and/or therapeutic treatment when combined with an appropriate radioactive metal ion such as ?99mTc, 186Re or 188¿Re.</p> |
