Co-expression of antibody fab heavy and light chain genes from separate evolved compatible replicons in E. coli.


Antibody molecules bind to antigen with six complementary determining region (CDR) loops, three of which are located on each variable heavy (V(H)) and light (V(L)) chains. Discovery and optimization of antibodies that bind antigen using in vitro techniques require diversification of one or more of these CDRs. Since antibodies are dimeric, simultaneous… (More)
