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.
An antigen is a substance which stimulates an immune response. When exposed to an antigen, the body views it as foreign material, and takes steps to neutralize it. Typically, the body accomplishes this by making antibodies, which are intended to defend the body from invasion by potentially dangerous substances.
