摘要： An immunoassay element for quantitatively analyzing a ligand by determining the change in enzymatic activity. When the ligand is a low molecular weight antigen, competitive reactions between the ligand, enzyme-labelled antibody and conjugate of the antigen and high molecular weight compound are utilized. When the ligand is a macromolecular antigen, a reaction between the ligand and an enzyme-labelled antibody is utilized directly. The immunoassay element comprises a substrate layer containing a non-diffusible substrate which forms a diffusible material in the presence of the enzyme, and a reagent layer for detecting the thus formed diffusible material. The non-diffusible substrate is composed of a pulverized insoluble polysaccharide. The reagent layer may further contain a fragmenting enzyme for further fragmenting the non-diffusible material. Also provided are processes for quantitatively analyzing both of low molecular weight and macromolecular antigens contained in any samples by the use of the immunoassay elements of the invention.

摘要： An analysis element for analyzing both amounts of glycated hemoglobin and total hemoglobin in an aqueous liquid sample to determine glycated hemoglobin content ratio in the sample. The element comprises a substrate layer for receiving a reaction mixture after the completion of an immunological reaction between the glycated hemoglobin in the sample and an enzyme-labelled antibody against the glycated hemoglobin, and a reagent layer. The substrate layer contains a non-diffusible substrate which forms a diffusible material in the presence of the enzyme of the enzyme-labelled antibody, the activity of the enzyme being effected relative to the steric hindrance due to the immunological reaction. The reagent layer contains a reagent composition for reacting with the diffusible material to form a dye detectable colorimetrically in a wavelength range which is not effected by an absorption spectrum of the hemoglobin. The total hemoglobin retained in the substrate layer and the dye formed in the reagent layer are colorimetrically analyzed separately, and the glycated hemoglobin content ratio is calculated from respective values. An analysis method using this analysis element is also provided.

摘要： An improved homogeneous enzyme immunoassay process for quantitatively analyzing an antigen by determining the change in the enzymatic activity caused by a reaction between the antigen and an enzyme-labeled antibody. The antigen is reacted with an enzyme-labeled antibody, followed by the reaction with a second antibody capable of recognizing and binding to a different epitope and then with a third antibody capable of recognizing and binding to the second antibody. The enzymatic activity of the labeling enzyme is determined by a water-insoluble substrate. Using the water-insoluble substrate, steric hindrance is enhanced. A highly-sensitive analysis can be carried out by a simple operation even when the antigen has a molecular weight falling within an intermediate range, for example, a range of M.W. 10,000 to 70,000.

摘要： A micro-array for analysis of DNA is prepared by the steps of spotting onto a solid carrier in its predetermined area in which plural reactive groups are fixed an aqueous solution which contains a thickening agent and probe molecules (e.g., DNA fragments) having a group reactive with the reactive group of the solid carrier to produce covalent bonding; spotting onto the solid carrier in a different area having the same reactive groups an aqueous solution (same or different); incubating the aqueous solution-spotted solid carrier to produce the covalent bondings; and washing the solid carrier with an aqueous medium to remove the thickening agent from the solid carrier. An electrostatic bonding can be utilized in place of the covalent bonding.

摘要： An agglutination assay method for quantitatively determination of an analyte in a liquid sample using particles bearing an anti-analyte. A non-fluid substance which retains the particles while suppressing the diffusion of the particles therein is used as a medium which is to be a place where the agglutination of the particles takes place. Upon analysis, a solation agent is added to the non-fluid substance medium to increase the fluidity of the non-fluid substance, thereby the particles bearing the anti-analyte can diffuse in the medium to cause the agglutination with the analyte. Preferably, the solation agent is added to the non-fluid medium together with the sample. The non-fluid substance medium containing the particle-labeled anti-analyte can be stored with a higher stability in the dry state. A dry analysis element for enabling such analysis method is also provided.
