Synthetic Antibodies in Infectious Disease

Rapid spread of microbial resistance and recent outbreaks of viral disease have led to renewed interest in antibody-based therapies for infectious diseases. Synthetic antibody libraries displayed on phage offer unique advantages over traditional immunization-based antibody generation, including full control over library design and selection conditions. The technology has matured beyond natural antibodies and is capable of providing novel insights into infectious disease and can generate novel antibodies that cannot be produced by the natural immune system. This chapter gives an overview of recombinant antibody library technology with an emphasis on our work using a highly successful synthetic single framework Fab library. We demonstrate its utility in targeting viruses and bacterial toxins in five case studies.
