Abstract
Recombinant antibody libraries based on chicken immunoglobulin genes are potentially valuable sources of phage-displayed scFvs for use in veterinary diagnostics and research. To add diversity to the scFv repertoire, we expanded the library to include genes from the ostrich, indigenous to southern Africa. The libraries described in this chapter are based on the chicken and ostrich variable heavy and light chain immunoglobulin genes joined by a short flexible linker cloned in the phagemid vector pHEN1. The resulting phagemids produce either scFvs displayed on the surface of the fusion phage subsequent to co-infection with helper phage or soluble scFvs following IPTG induction. This chapter provides detailed and proven methods for the construction of such libraries.
