Publication number: 20240036039Abstract: Described are sensing devices and methods for detecting at least one analyte in a sample solution. The sensor is capable of a pre-storage state, a storage state and a sensing state. The sensor includes at least one substrate-adjacent aptamer; where the sensor, in the absence of a material to reduce or prevent degradation, would incur significant degradation when the sensor is placed in a storage state. The sensor further includes at least one material which reduces or prevents the significant degradation during the storage state.Type: ApplicationFiled: October 2, 2020Publication date: February 1, 2024Inventors: Jason Heikenfeld, Mark Friedel, Zachary Watkins

Publication number: 20240036040Abstract: Provided is an easy to determine immunochromatography detection device that detects a target substance that may be contained in a sample fluid. The detection device includes a flow path for the sample fluid and detection parts 1 to which capture selected substances. In one embodiment, an Metal-Insulator-Metal (MIM) structure is formed when the target substance is included in the sample fluid at the detection parts, and a color is produced at the detection parts by resonance absorption. The MIM structure comprises a metal thin film (M layer) that is formed on a support that acts as either a capture substance/target substance/reference substance composite layer or a capture substance/reference substance composite layer (I layer), and metal fine particles (M layer) with which a reference substance is labeled.Type: ApplicationFiled: December 16, 2021Publication date: February 1, 2024Inventor: Takuo TANAKA

Publication number: 20240036041Abstract: The present disclosure generally provides methods for identifying compounds that enhance kokumi taste, and related uses. In some particular aspects, the disclosure provides methods of identifying compounds that enhance kokumi taste by determining whether the compounds modulate the T1R1/T1R3 taste receptor. In some other aspects, the disclosure provides uses of such identified compounds to enhance the kokumi taste of an ingestible composition. In some further aspects, the disclosure provides flavored products, such as food or beverage products, that incorporate such ingestible compositions, and which thereby impart or enhance an umami taste in a flavored article. In some other aspects, the disclosure provides ingestible compositions that contain compounds known to impart or enhance umami taste, such as glutamates, aspartates, and purinic ribonucleotides, such as inosine monophosphate (IMP) and guanosine monophosphate (GMP).Type: ApplicationFiled: November 19, 2021Publication date: February 1, 2024Inventors: Guy Servant, Eric Frerot

Publication number: 20240036043Abstract: The present disclosure relates to a method for identifying cells that express antigen-specific antibodies with a high binding affinity for a monomeric antigen. Using fluorescence activated cell sorting, cells expressing high affinity antigen-specific antibodies are selected from a population of immune cells isolated from a mammal that has been immunized with or otherwise exposed to the antigen. Nucleic acids encoding the high affinity antibodies can then be cloned into other lymphoid and non-lymphoid cells where the antibody can be expressed and from which the antibodies can be secreted.Type: ApplicationFiled: October 2, 2023Publication date: February 1, 2024Applicant: Regeneron Pharmaceuticals, Inc.Inventors: Gang CHEN, Robert BABB, James P.
