Ryo Shida 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).

  • Patent number: 7972872
    Abstract: This invention provides an immunochromatography detection apparatus exhibiting excellent convenience, sensitivity, and specificity, a detection method therefore, a kit using the same, and a method for producing such apparatus and kit, by constructing a solid-phase support, on which the conditions for the reaction wherein an analyte specifically binds to a labeled reagent containing a ligand that specifically binds to the analyte and those for the reaction wherein a capture reagent specifically binds to a complex of the analyte and the labeled reagent in the immunochromatography detection method are continuously optimized, and the pretreated specimens are optimized for such reactions.
    Type: Grant

  • Patent number: 7718444
    Abstract: This invention provides a simple detection method with excellent sensitivity and specificity, which allows prompt detection of an analyte by allowing a labeled reagent to effectively react with the analyte in the process of treating an analyte-containing specimen, such as during removal of impurities, a detection apparatus, and a detection kit. This method for detecting an analyte in specimens comprises steps of: bringing a labeled reagent containing a ligand that specifically binds to the analyte into contact with a specimen; and supplying the mixture of the specimen and the labeled reagent to a solid-phase support onto which a capture reagent that specifically binds to the analyte has been immobilized, wherein the step of bringing the specimen into contact with the labeled reagent is carried out at a site that is not on the solid-phase support and that is detached from the solid-phase support.
