The bifunctional chelating agents (BFCs), 6-[p-(bromoacetamido)benzyl]-1,4,8,11-tetraazacyclotet-
radecane-1,4,8,11-tetraacetic acid (BAT), 6-[p-(isothiocyanato)benzyl]-1,4,8,11-tetraazacyclotetradecane-
1,4,8,11-tetraacetic acid (SCN-TETA), 4-[(1,4,8,11-tetraazacyclotetradec-1-yl)methyl]benzoic acid
(CPTA), and 1-[(1,4,7,10,13-pentaazacyclopentadec-1-yl)methyl]benzoic acid (PCBA), were synthesized
and conjugated to the anti-colorectal monoclonal antibody (mAb), 1A3, and antibody fragments, 1A3-
F(ab)2, for radiolabeling with 64,67Cu and comparison in animal models. In vivo metabolism studies
