Patent number: 11925041Abstract: To provide a light-emitting element with high emission efficiency and low driving voltage. The light-emitting element includes a guest material and a host material. A LUMO level of the guest material is lower than a LUMO level of the host material. An energy difference between the LUMO level and a HOMO level of the guest material is larger than an energy difference between the LUMO level and a HOMO level of the host material. The guest material has a function of converting triplet excitation energy into light emission. An energy difference between the LUMO level of the guest material and the HOMO level of the host material is larger than or equal to energy of light emission of the guest material.Type: GrantFiled: December 18, 2020Date of Patent: March 5, 2024Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Satoshi Seo, Takeyoshi Watabe, Satomi Mitsumori

Patent number: 11702684Abstract: The present invention pertains to an enzymatic measurement method using an antibody-enzyme complex or a nucleic acid probe measurement method using an enzyme-labeled nucleic acid probe, in both of which the quantification of a product of a reaction by an enzyme in the antibody-enzyme complex or the enzyme-labeled nucleic acid probe is performed by generating thio-NAD(P)H by an enzymatic cycling reaction using NAD(P)H, thio-NAD(P), and a dehydrogenase (DH), and measuring the amount of the generated thio-NAD(P)H or measuring a change in color caused by the generated thio-NAD(P)H. An enzymatic reaction system in which NAD(P) generated from NAD(P)H by the enzymatic cycling reaction is selectively reduced, is caused to coexist with the enzymatic cycling reaction. The present invention also pertains to a kit for enzyme immunoassay, and a kit for nucleic acid probe measurement.Type: GrantFiled: March 7, 2017Date of Patent: July 18, 2023Assignee: BioPhenoMA Inc.Inventors: Etsuro Ito, Toshiaki Miura, Teruki Yoshimura, Satoshi Watabe

Patent number: 11221299Abstract: Provided is a ultra-high-sensitivity assay in which the assay can be made on a commonly used assay apparatus such as an absorptiometer and a plate reader or with naked eyes. The high-sensitivity assay in which the assay can be made on a commonly used assay apparatus or with naked eyes can be provided by combining an enzyme cycling method using thio-NAD(P) as a coenzyme, a labeling enzyme and a substrate for the labeling enzyme optimally, and by amplifying thio-NAD(P)H, which is a signaling substance, exponentially and then quantifying the thio-NAD(P)H colorimetrically.Type: GrantFiled: December 18, 2017Date of Patent: January 11, 2022Inventors: Etsuro Ito, Satoshi Watabe, Toshiaki Miura, Teruki Yoshimura
