Each antibody binds to a specific antigen; an interaction similar to a lock and key. An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein produced mainly by plasma cells that is used by the immune system to identify and neutralize pathogens such as bacteria and viruses.
By definition, antibodies bind to specific antigens. In the case of an antibody which fights viruses, the antigen is a specific viral protein. Antibodies bind the HA, the important receptor-binding protein of the influenza virus, blocking it so it can't infect other cells.y definition, antibodies bind to specific antigens.
