Abstract:
Recombinant antibody libraries based on chicken immunoglobulin genes are potentially valuable sources of phage displayed scFvs for use in veterinary diagnostics and research. The libraries described in this chapter are based on chicken 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.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
