Interest in recombinant antibody technologies has rapidly increased because of the wide range of possible applications in therapy and diagnosis, especially in cancer treatment. The possibility of generating human antibodies that are not accessible by conventional polyclonal or monoclonal approaches has forced the development of antibody engineering technologies even more.This manual presents a comprehensive collection of detailed, step-by-step protocols provided by experts in the field. All basic methods needed in antibody engineering - not only methods to generate recombinant antibodies, but also protocols for analysis and their use - and recently developed and emerging technologies are covered.
