Site-specific attachment to recombinant antibodies via introduced surface cysteine residues

Abstract excerpt

Many diagnostic and therapeutic applications of monoclonal antibodies require the covalent linking of effector or reporter molecules to the immunoglobulin polypeptides. Existing methods generally involve the non-selective modification of amino acid side chains, producing one or more randomly distributed attachment sites. This results in heterogeneous labelling of the antibody molecules and often to a decrease in...
