Abstract: An object of the present invention is to provide a method for preventing the generation of negative signals because of dissociation of a ligand from a surface and improving the precision of signals indicating binding between a ligand and an analyte. The present invention provides a method for immobilizing a biomolecule on a carrier having reactive groups which comprises: (i) a step of activating some reactive groups so that they can form a covalent bond with a biomolecule; (ii) a step of reacting the biomolecule with the aforementioned activated reactive groups; and (iii) a step of again activating some reactive groups; wherein the steps (i), (ii) and (iii) are performed in this order.

Abstract: It is an object of the present invention to provide a method for measuring the interaction between a physiologically active substance immobilized on the surface of a substrate and a test substance, wherein the influence of negative signals intermittently generated due to desorption of the physiologically active substance as a ligand from the surface of the substrate upon the measured value that indicates the binding amount of a test substance as an analyte can be eliminated. The present invention provides a method for measuring the interaction between a physiologically active substance immobilized on the surface of a substrate and a test substance, wherein a calibration curve is produced by using baseline values obtained by repeatedly measuring a single type of solution, and the measurement value of said test substance is calibrated by said calibration curve, so as to obtain the interaction signals of said test substance.
