Abstract
Two novel approaches of recombinant PCR technology were employed to graft the complementarity determining regions from a murine monoclonal antibody (mAb) onto human antibody frameworks. One approach relied on the availability of cloned human variable region templates, whereas the other strategy was dependent only on human variable region protein sequence data. The transient expression of recombinant humanized antibody was driven by the adenovirus major late promoter and was detected 48 hrs post-transfection into non-lymphoid mammalian cells. The application of these new approaches enables the expression of a recombinant humanized antibody just 6 weeks after initiating the cDNA cloning of the murine mAb.
