Antibody engineering is a biotechnological process that involves modifying antibodies to improve their effectiveness in targeting specific diseases, such as cancer or autoimmune disorders. This technique allows scientists to enhance the binding affinity, stability, and specificity of antibodies, making them more effective as therapeutic agents. Researchers use various methods, including recombinant DNA technology and phage display, to create engineered antibodies. These modified antibodies can be designed to recognize and bind to particular proteins on the surface of pathogens or tumor cells, leading to improved treatment options and better patient outcomes.
