Antibodies are host proteins that are produced by the immune system in response to foreign molecules that enter the body. These foreign molecules are called antigens, and their molecular recognition by the immune system results in selective production of antibodies that are able to bind the specific antigen.his ability of animal immune systems to produce antibodies capable of binding specifically to antigens can be harnessed to manufacture probes for detection of molecules of interest in a variety of research and diagnostic applications.
