Agglutination
Antibodies coagulate the pathogens and make them an easy target to be trapped and destroyed by phagocytosis.
Neutralisation
Antibodies bind with toxins produced by bacteria and neutralise the toxin.
Precipitation
Antibodies react with dissolved antigens to form an insoluble complex (precipitate) that is easily destroyed by phagocytes.
Opsonisation
Antibodies combine with antigens and act as a marker for phagocytes to recognise the antigens and destroy them.
Lysis
Antibodies combine with antigens and cause bacteria to be broken down and decomposed.
Action of antibodies
Antigens are destroyed by antibodies through several mechanisms that involve the process of agglutination, neutralisation, precipitation, opsonisation and lysis.
