The present invention provides a method for the preparation of radioisotopically-labelled imaging agent compositions. The method uses precursors which are bound to soluble polymers, so that the radiolabelling reaction is carried out in solution. Also described are radiopharmaceutical compositions, automated versions of the radiolabelling method and disposable cassettes for use in the automated method.
Disclosed is a capture reagent having Formula I:
PRG-L-X-carrier (I)
wherein:
PRG is a peptide or protein reactive group;
L is a linker group comprising a stable isotopic detectable label moiety; and
X is a cleavable group.
Also disclosed is a method for selective labelling and purification of proteins and peptides comprising using a capture reagent of Formula I.
