A method of immunoassaying with the use of insoluble magnetic support particles which is appropriate for saving labor or treating a large number of specimens within a short time while avoiding problems in the stability of sensitized insoluble magnetic particles or difficulties in preparation. In assaying an antigenic substance in test samples, use is made of not insoluble magnetic support particles carrying an antibody specific to the antigenic substance but insoluble magnetic support particles in a state where the antibody, etc. are substantially not adsorbed. Then the antigenic substance to be assayed per se is adsorbed by the insoluble magnetic support particles and the adsorbed antigenic substance is reacted with a labeled antibody specific thereto. Thus, the antigenic substance in the test samples can be efficiently assayed in a mode suitable for automation.

La présente invention concerne un procédé de dosage immunologique au moyen de particules de support magnétiques insolubles permettant la simplification de l'opération ou le traitement d'un grand nombre de spécimens en un court laps de temps tout en évitant les problèmes de stabilité de particules magnétiques insolubles ou des problèmes de préparation. Lors du dosage d'une substance antigénique dans des échantillons pour essai, on utilise des particules de support magnétiques non insolubles portant un anticorps spécifique de la substance antigénique mais des particules de supports magnétiques dans un état dans lequel l'anticorps et analogues ne sont pas sensiblement adsorbés. Ensuite on effectue l'adsorption de la substance à doser elle-même par les particules de support magnétiques insolubles et on fait réagir la substance antigénique avec un anticorps marqué qui lui est spécifique. Ainsi la substance antigénique dans les échantillons pour essai peut être efficacement dosée dans un mode capable d'être automatisé.
