Monoclonal antibody 3E1.2 was coupled with the bifunctional chelate, cyclic DTPA anhydride, at molar ratios (cOTPAA:3E1.2) of 1:1, lO:l, 1OO:l and 1oOO:l. The desired substitution level of less than one mol of D"PA/bl of 3E1.2 was achieved at a molar ratio of 1O:l and a coupling efficiency of 9.9t3.
