From the mouse hybridoma cell line secreting an anti-CD4 monoclonal antibody (McAb), total RNA was prepared. The VH and VL genes were amplified by RT-PCR with family specific primer pairs. The PCR products were cloned into pGEM-T vectors, then tranfected into JM109. The VH and VL genes were analyzed by automatic DNA sequencer. According to Kabat classification, the VH and VL genes belong to the mouse Ig heavy subgroup II (A) and kappa chain subgroup III, respectively. The VH and VL genes were subcloned into p gamma 1-Expr and p kappa-Expr respectively, then transfected into XL2-Blue. The VH- p gamma 1 and VL- p kappa were transfected by electroporation into mouse myeloma cell X63Ag8. 653. The transfectoma cells were selected by G418 screening, and then supernatant of cultured transfectoma were analyzed by ELISA and immunofluorescence techniques. We have acquired transfectoma cells secreting anti-CD4 chimeric antibodies. These chimeric antibodies are able to kill tumor cells specifically in vitro.
