The present invention relates to a method for radioactive labeling of a protein or peptide, by providing a protein or peptide having at least one glutamine or lysine residue; adding a metal chelating agent having at least one lysine or glutamine residue, respectively, which metal chelating agent is optionally complexed with a radioactive or paramagnetic metal; reacting the protein or peptide and metal chelating agent in the presence of a transglutaminase to obtain a protein or peptide with a metal chelating group covalently bound thereto, and optionally complexing the metal chelating group with a radioactive or paramagnetic metal. The invention also relates to proteins and peptides thus labeled and to proteins and peptides that have been coupled to a metal chelating agent but not yet labeled.
