Masahito Nagata has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20100317126
    Abstract: An agglutination assay method for quantitatively determination of an analyte in an aqueous liquid sample using particles bearing an anti-analyte. The agglutination is conducted in the porous medium layer of the analysis element. A speedy quantitative analysis of the analyte can be conveniently attained with high sensitivity. When the particle-labeled anti-analyte is contained in the porous medium layer, the anti-analyte can be stored with higher stability in the dry state. A dry analysis element for enabling such analysis method is also provided.

  • Publication number: 20050153460
    Abstract: An agglutination assay method for quantitatively determination of an analyte in a liquid sample using particles bearing an anti-analyte. The agglutination is conducted in a reagent layer composed of at least one binder selected from the group consisting of: a water-soluble polymer having a solution viscosity of 6 cP or less; a water-insoluble and water-swellable polymer; and gelatin having a molecular weight of 20,000 or less. A speedy quantitative determination of the analyte can be conveniently attained with high sensitivity. When the particle-labeled anti-analyte is contained in the reagent layer medium, the anti-analyte can be stored with higher stability in the dry state. A dry analysis element for enabling such analysis method is also provided.
