immunoprecipitin analysis

(ĭm″ū-nō-prē-sĭp′ĭ-tĭn, ĭ-mū″) An immunoassay in which the antibody-antigen reaction forms a visible substance that drops out of solution. This is most commonly represented by turbidity in a liquid matrix or a band of turbidity in a gel matrix. The amount of turbidity or the size of the band allows quantification.
