Step agglutination immunoassay

   
   

An immunoassay for detecting an antigen in a sample, by: (a) sequentially contacting the sample with (i) a first antibody which is capable of specifically binding to a first binding site on the antigen, and then (ii) a second antibody which is capable of specifically binding to a second binding site on the antigen, thereby forming, when the antigen is present in the sample, an agglutinate comprising the first antibody, the antigen, and the second antibody; followed by (b) optically measuring the amount of the agglutinate.

Un immunoassay para detectar un antígeno en una muestra, cerca: (a) secuencialmente entrando en contacto con la muestra con (i) un primer anticuerpo que es capaz específicamente de atar a un primer sitio obligatorio en el antígeno, y entonces (ii) un segundo anticuerpo que es capaz específicamente de atar a un segundo sitio obligatorio en el antígeno, de tal modo formando, cuando el antígeno está presente en la muestra, una aglutinación que abarca el primer anticuerpo, el antígeno, y el segundo anticuerpo; seguido (b) ópticamente midiendo la cantidad de la aglutinación.
