Qinxue DING 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: 11835517
    Abstract: Methods and kits for accurately detecting one or more analytes in a sample by removing non-specific binding signals utilizing capture and control microparticles. The capture microparticles can specifically bind to the analyte while the control microparticles do not specifically bind to the analyte but to the background molecules. Both capture and control microparticles are added to the sample under suitable conditions to allow binding between analytes and the microparticles. Detection agent is then added to bind to analytes and other substances captured by the microparticles. The microparticles are then run through a cytometry-based detection method, where detection signals from the capture and the control microparticles are distinguished.
    Type: Grant
