Antigen—antibody reactions in vitro
- 147 Downloads
Antigen can react with antibodies in vivo or in vitroin vitro. The in vivo reaction can be beneficial for the organism (immunity), harmful (immunopathological reactions) or indifferent (immune system tolerates, rather than responds to the antigen). The in vitro reactions are the basis for immunochemical methods which depend on biospecific binding between binding sites of the antibody and determinant groups of the antigen resulting in formation of antibody-antigen complexes (immune complexes).
