Title
(EN) ASSAY METHOD AND APPARATUS
(FR) PROCEDE ET APPAREIL DE DOSAGE
Abstract
(EN) A method of assaying for an analyte including the steps of: (i) passing a sample suspected of containing an analyte and reagents comprising a target ligand-analyte receptor conjugate and a detectable tracer containing a label for the analyte through filter apparatus containing a plurality of discrete flow zones wherein at least one zone functions as a capture zone having bonded thereto a receptor ligand for said target ligand; (ii) allowing the sample and accompanying reagents to incubate prior to passage through said at least one zone to facilitate formation of complex(es) of said conjugate and said at least one analyte in a liquid or fluid phase; and (iii) detecting the presence of analyte in the sample by activation of the label in said at least one zone after binding of the complex(es) conjugate to the associated receptor ligand(s).
(FR) L'invention concerne un procédé permettant de doser un analyte, comprenant les étapes consistant à: (i) faire passer un échantillon, dont on pense qu'il contient un analyte, et des réactifs, comprenant un conjugué ligand cible-récepteur d'analyte et un traceur détectable contenant un marqueur destiné à l'analyte, à travers un appareil de filtration contenant une pluralité de zones d'écoulement séparées, au moins une de ces zones fonctionnant en tant que zone de captage à laquelle est lié un ligand de récepteur, pour ledit ligand cible; (ii) laisser incuber l'échantillon et les réactifs qui l'accompagne avant le passage à travers la ou lesdites zones de captage pour faciliter la formation d'un complexe (ou de complexes) dudit conjugué et du ou des analytes en phase liquide ou fluide; et (iii) détecter la présence d'analyte dans l'échantillon par activation du marqueur dans la ou dans lesdites zones de captage, après liaison du ou desdits complexes au(x) ligand(s) de récepteur associé(s).
