A method for conducting a receptor-ligand association reaction includes the steps of pressurizing a reaction solution containing a ligand or receptor labeled with a labeling substance such as a radioactive labeling substance, a fluorescent substance or a labeling substance which generates chemiluminescence emission when it contacts a chemiluminescent substrate and forcibly feeding the reaction solution so as to cut through a plurality of absorptive regions formed in a biochemical analysis unit to be spaced from each other and containing receptors or ligands, thereby selectively associating the ligand or receptor contained in the reaction solution with the receptors or ligands contained in the absorptive regions of the biochemical analysis unit. According to this method, it is possible to efficiently associate a ligand or receptor with receptors or ligands fixed in the absorptive regions of the biochemical analysis unit and produce biochemical analysis data having an excellent quantitative characteristic with good repeatability.
