A NEW BIFUNCTIONAL CHELATING AGENT α,ε-N,N'-BIS(L-CYSTEINYL)-L-LYSINE FOR RADIOLABELLING OF MONOCLONAL ANTIBODIES WITH TECHNETIUM-99M
α,ε-N,N’-bis（L-cysteinyl）-L-lysine was synthesized and char-acterized for the first time.It was then employed as a bifunctional chelatingagent to chelate technetium-99m and subsequently conjugated to fragmentF（ab’）2 of anti-gastric tumor monoclonal antibody 3G9.The radiolabelledantibody was satisfactorily stable and immunoreactive.
