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.

β¦ Synopsis
Polymeric paramagnetic ion chelate molecules were synthesized and covalently linked to monoclonal antibodies. The labeled antibodies retained their antigen binding capacity in vitro while carrying up to an average of 50 paramagnetic ion chelates, enabling specifically bound antibody concentrations less than 2.0 pM to significantly reduce proton longitudinal relaxation times. o 1986 Academic press.
