  • Patent number: 8038945
    Abstract: To provide a method for detecting a protein by immobilizing a protein on a protein array substrate at a high density with controlled orientation, irradiating the immobilized protein with ultraviolet light, visible light, or infrared light, and measuring the light not absorbed by the protein and further analyzing an interaction between the protein on the substrate and another protein and/or a compound other than proteins, a system used for the method, and to provide a protein array suitable for the system.

  • Publication number: 20100130721
    Abstract: This invention provides an immobilized protein bound to an immobilization carrier at a protein amino terminus via the sole ?-amino group of the protein comprising an amino acid sequence containing neither lysine residues nor cysteine residues represented by the general formula S1-R1-R2, wherein: the sequences are oriented from the amino terminal side to the carboxy terminal side; the sequence of the S1 portion may be absent, but when the sequence of the S1 portion is present, the sequence of the S1 portion is a spacer sequence composed of amino acid residues other than lysine and cysteine residues; the sequence of the R1 portion is the sequence of a subject protein to be immobilized and contains neither lysine residues nor cysteine residues; and the sequence of the R2 portion may be absent, but when the sequence of the R2 portion is present, the sequence of the R2 portion is a spacer sequence composed of amino acid residues other than lysine and cysteine residues.

  • Publication number: 20080146459
    Abstract: A protein array having a protein aligned and immobilized in high density and in uniformly oriented form is produced by introducing a polymer compound having a primary amino group as a repeating unit on the surface of a planar substrate so as to obtain a substrate for protein array and binding the carboxyl terminal of the main chain of a protein with the primary amino group of the polymer compound on the substrate.

  • Publication number: 20080051555
    Abstract: A support having an affinity for an antibody characterized in that the carboxy end of a protein or a peptide, which is capable of binding to an antibody molecule, is immobilized via an amide bond mediated by a linker sequence to an insoluble support having a primary amino group. This support has an excellent ability to adsorb antibody molecules.
