    摘要： Chimeric human antibody expression vectors are constructed by inserting the heavy chain variable region-encoding cDNA and antibody light chain variable region-encoding cDNA isolated from hybridomas producing a mouse or rat monoclonal antibody reacting with the ganglioside GM2 respectively into an expression vector which contains the human antibody heavy chain constant region- or human antibody light chain constant region-encoding cDNA. The expression vectors are introduced into animal cells and the transformant thus obtained is cultured to produce a chimeric human antibody reacting with the ganglioside GM2. In contrast to mouse monoclonal antibodies, the chimeric human antibodies of the invention will not cause anti-mouse immunoglobulin antibody production in the patient's body but show a prolonged blood half-life, with a reduced frequency of adverse effects, so that it can be expected to be superior to mouse monoclonal antibodies in the efficacy in the treatment of human cancer, for instance.
