ABSTRACT:
This invention relates to chelating agents useful for coupling metal ions to biologically active molecules. In particular, isothiocyanate derived thiocarbonyls for chelating metals such as technetium are provided that can be conjugated to a targeting molecule such as an antibody, a peptide or a protein.
