The Antibodies presents models, theories, and techniques of molecular biology for understanding the mechanisms of antibody action, including the genetics, and receptor and channel action. This book includes applications of engineered antibodies in diagnosis, immunotherapy, and protein purification. It provides new insights into the structural basis for antigen binding, effector functions, and regulation of the immune response. The authors focus on the most essential and promising advances in antibody engineering, and on building immunoglobulins for therepeutic applications.
