This invention concerns novel labeling reactants suitable for labeling of a biospecific binding reactant using solid-phase synthesis. The novel reactants are derivatives of diethylenetriaminepentaacetic acid (DTPA), wherein a suitable group is linked to the DTPA molecule, thus allowing site specific introduction of the ligand of the derivatives to bioactive molecules on solid phase in an oligopeptide synthesizer.
