Production of monoclonal antibodies to C3d usually involves the purification of protein. Our method does not require C3 purification; it relies on attachment of C3b to mouse erythrocytes by activation of alternative pathways and further conversion in C3d. We prepared human complement-coated mouse red cells and sensitized mice of the same strain with our own schedule of immunization and applied the classical methods to obtain a mouse monoclonal antibody. We obtained a clone called BMS-11 which produces a monoclonal antibody of IgM class, to C3d with a title of 1:500000. The monoclonal antibody obtained has shown that it is suitable for use as an antiglobulin reagent.
