A Small molecules can be recognized by antibody but cannot stimulate the immune system to produce antibody. B They must conjugate with carrier protein to form an immunogen for production of a monoclonal, polyclonal, and recombinant antibodies. C The antibody is a Y-shaped molecule composed of four polypeptide subunits with two identical heavy and light chains. D Type of immunoassay used for CPF detection
