 AB    We present an easy and efficient technique for the construction of large
       phage-displayed antibody (Ab) repertoires through the recombination of
       two separate heavy (VH) and light (VL) chain gene libraries. Here, the
       system has been applied to the display of a chimpanzee anti-HIV gp160
       Ab. The process, which makes use of lambda phage att recombination
       sites, leads to the irreversible physical association between plasmid
       and phagemid vectors carrying, respectively, VL and VH sequences. The
       heat-inducible expression of the Int recombinase allows perfect control
       of recombination. Selection of the recombinant phagemid is made possible
       by the assembly, in vivo, of a genetic marker (chloramphenicol
       resistance) created only after the correct recombination event.
       Theoretically, all possible associations between the VL and VH sequences
       should be obtained, and it should be possible to generate
       multicombinatorial libraries of close to 10(12) clones.
