Explanation:
Detailed explanation-1: -Precipitation refers to the creation of clearly visible insoluble lattices or cross-linkages, whereas agglutination refers to the formation of huge solid clumps as a result of antibody-antigen interaction.
Detailed explanation-2: -Precipitation reaction Soluble antigens combine with soluble antibodies in presence of an electrolyte at suitable temperature and pH to form insoluble visible complex. This is called a precipitation reaction.
Detailed explanation-3: -Antigen-antibody precipitates, prepared either in solution in antibody excess or by cutting precipitin lines from immunoelectrophoretic plates have been shown to bind specifically to the homologous antigen in tissue sections.
