  • Patent number: 11698375
    Abstract: A method for producing an examination reagent includes adding a helper ligand to a receptor protein which is unfolded in an initial solution so as to provide a pre-solution of the examination reagent with a receptor protein which is folded. The receptor protein which is folded comprises a bonded helper ligand which can be exchanged with an examination peptide.

  • Publication number: 20220050104
    Abstract: A method for detecting T cells includes a first step of bringing a plurality of different antigenic peptides into contact with peptide-free MHC molecules which are arranged in an immobilized manner on a substrate in an array so that the plurality of different antigenic peptides bind to the peptide-free MHC molecules so as to form peptide-loaded MHC molecules, a second step of bringing a sample comprising the T cells into contact with the peptide-loaded MHC molecules on the substrate, and a third step of detecting the binding of the T cells to the peptide-loaded MHC molecules on the substrate.
