  • The variable heavy and light chain genes of a monoclonal, IgM, anti-MAG antibody from a patient with neuropathy were inserted into expression vectors containing the gamma and kappa constant regions respectively and co-transfected into monkey kidney CV1P cells. The expressed antibody had the same antigenic specificity but significantly lower avidity than the native IgM, anti-MAG, antibody as detected by ELISA. When the variable heavy chain gene of the anti-MAG antibody was co-transfected with the variable light chain gene from another monoclonal, IgM, anti-MAG antibody, a fully assembled antibody was expressed as determined by a trapping ELISA, but it did not bind to (MAG) or to sulfated glucuronic acid paragloboside, indicating that both heavy and light chains contribute to the binding activity.
