precipitin

 [pre-sip´ĭ-tin]
an antibody to antigen that specifically aggregates the antigen in vivo or in vitro to give a visible precipitate.
precipitin reaction a reaction involving the specific serologic precipitation of an antigen in solution with its specific antiserum in the presence of electrolytes. The reaction is used in the typing of pneumococcus strains, in testing whether blood is human or animal, and for diagnostic purposes.
precipitin test any test in which the positive reaction consists of the formation and deposit of a precipitate in the fluid being tested. See also precipitin reaction.
