Involving Avidin-biotin Binding Patents (Class 435/7.5)
  • Patent number: 8288114
    Abstract: The present invention aims to provide a convenient and low-cost method for detection of a wide variety of compounds interacting with a target molecule located on a cell membrane, using a living cell without need of separating the cell membrane or the like from the cell. The present invention also aims to provide a kit for carrying out the method of the present invention. The method for detection of the compound interacting with the molecule located on the cell membrane in the present invention comprises steps of, allowing a compound having a moiety capable of binding selectively to the molecule located on the cell membrane and a radicalization-promoting moiety, to act on the cell; further allowing a compound having a group capable of being radicalized by the radicalization-promoting moiety and a labeling group, to act on the cell; and identifying the interacting compound bound by the compound radicalized by the radicalization-promoting moiety.

  • Patent number: 8283156
    Abstract: The present invention relates to a method and apparatus for detecting analytes in a medium, and more particularly the present invention relates to an assay based on light diffraction which appears or changes upon the binding of analytes to their specific receptors laid out in patterns on a substrate, which has high sensitivity due to the appropriate choice of such patterns. The present invention is based on the principle that the pattern of recognition elements, which gives rise to the diffraction of the incident light in a diffraction-based assay, can be chosen in such a way so as to facilitate detection, and to enhance the signal to be detected compared to known gratings such as parallel straight lines. In one aspect the substrate itself has a surface topography designed to enhance the diffraction pattern signals. In another aspect the substrate is a diffractive optic element having the analyte-specific receptors affixed to the optic element.

    Abstract: The invention relates to a microfabricated device for the rapid detection of DNA, proteins or other molecules associated with a particular disease. The devices and methods of the invention can be used for the simultaneous diagnosis of multiple diseases by detecting molecules (e.g. amounts of molecules), such as polynucleotides (e.g., DNA) or proteins (e.g., antibodies), by measuring the signal of a detectable reporter associated with hybridized polynucleotides or antigen/antibody complex. In the microfabricated device according to the invention, detection of the presence of molecules (i.e. Polynucleotides, proteins, or antigen/antibody complexes) are correlated to a hybridization signal from an optically-detectable (e.g. fluorescent) reporter associated with the bound molecules. These hybridization signals can be detected by any suitable means, for example optical, and can be stored for example in a computer as a representation of the presence of a particular gene.

  • Patent number: 8110406
    Abstract: [PROBLEMS] To reduce the amount of, for example, a capturing antibody to be employed without lowering detection sensitivity. At the same time, to enable the achievement of intense color development or light emission in a determination area even in the case where only a small amount of a labeled antibody is accumulated. To lower the detection limit in the sandwich method. To enlarge the dynamic range in the competition method. [MEANS FOR SOLVING PROBLEMS] A method of analyzing a test substance by an immunological analysis method by using the test substance, a support having a determination area, on which one member selected from a capturing antibody capable of binding specifically to the test substance and a capturing antigen capable of binding specifically to the test substance has been immobilized, and a labeled antibody capable of binding specifically to the test substance, wherein a label having a sensitizing effect has been immobilized on the determination area of the support.

  • Publication number: 20120021435
    Abstract: A method is disclosed for detecting circulating cells in a body fluid sample. In at least one embodiment, the method includes: filtering the body fluid sample through a porous membrane; transferring the porous membrane with the cells located thereon as filter residue to a cell culture vessel, wherein one surface of the cell culture vessel is coated with a first antibody which is directed to a first cell-specific marker; incubating the porous membrane in the cell culture vessel with a cell culture medium, wherein cell-specific markers released by any cells present are bound by the first antibody to produce a bound first cell-specific marker on the surface coated with the first antibody; removing the porous membrane with the cells located thereon as filter residue from the cell culture vessel; detecting the bound first cell-specific marker on the surface coated with the first antibody.

  • Publication number: 20120021416
    Abstract: Disclosed are methods and compositions for the ultrasensitive detection of oligonucleotides, proteins, protein complexes, biomolecules, and infectious agents using a peroxidase driven deposition of substrates onto interferometry capable biosensors, coupled to the specific recognition of the target molecules. More specifically, methods are disclosed to specifically immobilize biological target molecules onto the surface of interferometry capable biosensors and to associate the target molecules with peroxidase enzymes. Through the peroxidase driven deposition of substrates onto the interferometry capable biosensors there is the ability to achieve ultrasensitive detection and quantification of specific target molecules.

  • Publication number: 20120003666
    Abstract: Provided is a method of measuring a being state of a target substance at unknown concentration contained in a sample. The method includes identifying a kind of a target substance when one kind of target substance is contained in a sample and determining a concentration ratio when plural kinds of target substances are contained in the sample: by obtaining, with respect to each of plural kinds of known substances having the same recognition site, a relationship between Parameter A of the known substance and Parameter B of the known substance; and measuring Parameter A of the target substance contained in the sample and Parameter B of the target substance contained in the sample, wherein Parameter A of X is a value derived from a number of molecules of X and Parameter B of X is a value derived from the number and a molecular weight of X.
