A method of preparing a bispecific monoclonal antibody determinant comprising the steps of providing two different monoclonal antibody determinants, each determinant comprising two identical L-H half-molecules linked by one or more disulfide bond, subjecting the two different antibody determinants to conditions sufficient to break the disulfide bonds linking the L-H half-molecules, whereby each determinant is split into a pair of identical half-molecules, derivatizing one pair of identical half-molecules with a thiol activating agent, and combining the half-molecules to form the bispecific antibody determinants by the formation of one or more disulfide bonds. |
