A method for conducting a receptor-ligand association reaction includes the steps of forcibly feeding a reaction solution containing a ligand labeled with a labeling substance from one side of a biochemical analysis unit formed with a plurality of absorptive regions spaced apart from each other and containing receptors toward the other side thereof so as to cut through the absorptive regions of the biochemical analysis unit and forcibly feeding the reaction solution from the other side of the biochemical analysis unit toward the one side thereof via at least one check valve, thereby selectively associating the ligand contained in the reaction solution with the receptors contained in the absorptive regions. According to this method, it is possible to efficiently associate a ligand with receptors fixed in the absorptive regions of the biochemical analysis unit and produce biochemical analysis data having an excellent quantitative characteristic with good repeatability.
A method for conducting a receptor-ligand association reaction comprising the steps of forcibly feeding a reaction solution containing a ligand or receptor labeled with a labeling substance from one side of a biochemical analysis unit formed with a plurality of absorptive regions spaced apart from each other and containing receptors or ligands toward the other side thereof so as to cut through the plurality of absorptive regions of the biochemical analysis unit and forcibly feeding the reaction solution from the other side of the biochemical analysis unit toward the one side thereof via at least one check valve, thereby selectively associating the ligand or receptor contained in the reaction solution with the receptors or the ligands contained in the plurality of absorptive regions of the biochemical analysis unit.
A reactor for conducting a receptor-ligand association reaction comprising a reaction vessel provided with a biochemical analysis unit holding section formed with at least one check valve for holding a biochemical analysis unit formed with a plurality of absorptive regions spaced apart from each other and containing receptors or ligands and adapted for accommodating a reaction solution containing a ligand or receptor, and a solution feeding means for forcibly feeding the reaction solution accommodated in the reaction vessel from one side of the biochemical analysis unit held by the biochemical analysis unit holding section toward the other side of the biochemical analysis unit so as to cut through the plurality of absorptive regions of the biochemical analysis unit and forcibly feeding the reaction solution from the other side of the biochemical analysis unit toward the one side thereof via the at least one check valve.
