436523000 | Carrier is particulate and the particles are of intentionally different sizes or impregnated differently with the immunochemicals | 6 |
20080241963 | BIOCHEMICAL LABELING MATERIALS AND MANUFACTURING METHOD THEREOF - A biochemical labeling material and manufacturing method thereof. The manufacturing method provides a plurality of nanoparticles, bonding the nanoparticles to template molecules by molecular imprinting, polymerizing the nanoparticles to form a matrix with uniformly-distributed template molecules, finally removing the template molecules from the matrix to reveal a detection group of the matrix, leaving a cavity with specific area. | 10-02-2008 |
20090253220 | Absorbing Biomolecules into Gel-Shell Beads - Disclosed are ionic gel-coated beads (including Hydrogel™-coated beads), which are capable of adsorbing, or absorbing, proteins and other biomolecules onto or into the gel coating. The gel-coated beads with absorbed or adsorbed biomolecules are suitable for use in an assays, purification or other purposes. The beads have a core made from any of a number of materials, including latex, coated with the gel shell. The biomolecules can be retained within the gel, following adsorption, by covalent attachment, or, by selection of conditions of ambient pH and/or ionic strength such that they are retained without further reaction. Therefore, adsorbed proteins would retain the ability to bind to their respective ligands. | 10-08-2009 |
20100129937 | METHOD FOR MEASURING HYALURONIC ACID USING HYALURONIC ACID BINDING PROTEIN - An object of the present invention is to provide a method utilizing a carrier for measuring hyaluronic acid wherein deposition of carrier is less, a storage stability is good and an accuracy in measurement has same high degree as that performed by the conventional reagents, and a reagent kit for the same. Also, the present invention relates to “a method for measuring hyaluronic acid, comprising forming a hyaluronic acid/HABP complex by contacting hyaluronic acid in a sample with HABP, reacting said complex with an anti-HABP antibody-supported carrier, measuring optical change by agglutination product generated by said reaction and calculating the quantity of hyaluronic acid from the measured value” and “a reagent kit for the measurement of hyaluronic acid comprising a reagent comprising a hyaluronic acid binding protein and a reagent comprising an anti-hyaluronic acid binding protein antibody-supported carrier”. | 05-27-2010 |
20100178712 | Microplates containing microsphere fluorescence standards, microsphere standards, and methods for their use - Microplates containing spherical “microsphere” fluorescence standards are disclosed. The microplates can be prepared using several methods including airbrushing, application with an inkjet printer, or controlled evaporation. Spherical bead standards containing two or more regions stained with dyes of different fluorescence lifetimes, and methods for their preparation are also disclosed. The microplates can be used as calibration standards for fluorescence and confocal microscopes, and as calibration tools for microscope-based high content screening (“HCS”) instruments. | 07-15-2010 |
20110027915 | METHOD OF PRODUCING INSOLUBLE CARRIER PARTICLES, INSOLUBLE CARRIER PARTICLES, MEASUREMENT REAGENT, SPECIMEN ANALYZING TOOL, AND IMMUNOTURBIDIMETRIC ASSAY - The present invention provides a measurement reagent that is capable of suppressing nonspecific aggregation even when the amount of antibody to be carried is increased, and is capable of measuring in a wide measurement concentration range with high measurement sensitivity; an immunoturbidimetric assay using the same; and a method of producing thereof. A method of producing an insoluble carrier particle of the present invention is a method of producing an insoluble carrier particle carrying an antibody or an antigen on a particle surface thereof. The method includes a sensitization reaction processes in which the antibody or the antigen is brought into contact with the insoluble carrier particle in the presence of an amino acid with a charged polar side chain in a sensitization reaction solution. The insoluble carrier particles obtained by the producing method of the present invention show favorable dispersibility because nonspecific aggregation is suppressed. As can be seen from Examples 1-1 to 1-4 in FIG. | 02-03-2011 |
20110065213 | METHOD FOR IMMUNOASSAY USING LATEX PARTICLES - An object of the present invention is to provide latex particles with high production reproducibility, by which a sufficiently high value of signal ΔS (=value of signal−value of noise) can be realized in immunodiagnosis. The present invention provides a method for assay which comprises steps of (1) causing a substance to be detected to come into contact with or compete with binding substance-labeled fluorescent latex particles which are obtained by causing a binding substance to bind to fluorescent latex particles, and (2) measuring fluorescence from the binding substance-labeled fluorescent latex particles, wherein: (a) the fluorescent latex particles are obtained by adding a fluorescent substance to latex particles characterized in that the amount of COOH groups existing on the surfaces of the latex particles is from 40 μeq/g to 300 μeq/g, or (b) the fluorescent latex particles contain latex particles and a fluorescent substance, which are characterized in that the amount of COOH groups existing on the surfaces of the fluorescent latex particles is from 40 μeq/g to 300 μeq/g. | 03-17-2011 |
