^sup 111^In-Labeled antibodies and peptides have been routinely used as chemical and biologic surrogates for ^sup 90^Y-labeled therapeutic agents. However, recent studies have shown that there are significant differences in biodistribution between ^sup 111^In- and ^sup 90^Y-labeled agents. Yttrium and lutetium metals favor the +3 oxidation state, similar to indium, but there are minor differences in the solution and coordination chemistries among these metals. These 3 metals, however, form strong complexes with the macrocyclic chelator, 1,4,7,10-tetraazacyclododecane-N,N',N'',N'''-tetraacetic acid (DOTA). We, therefore, compared the pharmacokinetics and biodistribution of ^sup 111^In- and ...
