  • 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.

  • Patent number: 7501744
    Abstract: The present invention relates to a piezoelectric resonator system comprising a plurality of piezoelectric resonator sensors C?, C?. Each sensor C?, C? comprises an oscillator circuit 29?, 29? which is surrounded by its own individual conducting shield 44?, 44?. Each shield 44?, 44? is connectable to one pole of the power supply for its respective sensor C?, C?. These shields 44?, 44? prevent electromagnetic radiation from the sensors C?, C? from being transmitted through air.

  • 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.

  • Patent number: 7045931
    Abstract: The present invention relates to a chip quartz oscillator. In an embodiment of a chip quartz oscillator S in accordance with the present invention, a quartz oscillator 2, which has a detection electrode 3 on a surface thereof and a non-detection electrode on the other surface thereof, is fixed on a substrate 1, and each of the electrodes is connected electrically to a terminal 4 or 4? on the substrate 1. While keeping the non-detection electrode in contact with the substrate 1, the quartz oscillator 2 is fixed on the substrate 1, by flexibly bonding the side-wall 2?? of the quartz oscillator 2 along its circumference to the surface of the substrate 1 by using the elastic bonding agent 5. Thus, the oscillation surface of the quartz oscillator 2 is supported distributively on the substrate 1 in a surface-contacting and non-adhesive manner.
