An antibody is a substance produced by lymphocytes in response to an antigen so that it may destroy or control it.

Antibodies can neutralise antigens in a number of ways:

  • initiating lysis, or disentigration, of the antigen
  • neutralising bacterial toxins
  • coating the antigen
  • forming a complex to stimulate phagocytosis
  • promoting agglutination
  • preventing the antigen from adhering to host cells
