Abstract
Antibodies having binding affinity for two desired antigens, hereinafter "recombinant monoclonal antibodies"; recombinant monoclonal antibodies produced by a quadroma cell or a trioma cell; and methods for producing recombinant monoclonal antibodies by means of a quadroma cell or a trioma cell, wherein a quadroma cell is the fusion product of a hybridoma cell which produces an antibody having specific binding affinity to one desired antigen and a hybridoma cell which produces an antibody having specific binding affinity for another desired antigen, and wherein a trioma cell is the fusion product of a hybridoma cell which produces an antibody having specific binding affinity to one desired antigen and a lymphocyte which produces an antibody having specific binding affinity to another desired antigen.
