Definitions of P B Antibodies

  1. Antibodies elicited in a different species from which the antigen originated. These antibodies are directed against a wide variety of interspecies- specific antigens, the best known of which are Forssman, Hanganutziu- Deicher ( H- D), and Paul- Bunnell ( P- B). Incidence of antibodies to these antigens-- i. e., the phenomenon of heterophile antibody response-- is useful in the serodiagnosis, pathogenesis, and prognosis of infection and latent infectious states as well as in cancer classification.
