Abstract: The present invention is a test kit for rapidly diagnosing influenza according to the principles of immunochromatography, and the purpose thereof is to provide a test kit for the influenza A virus in which the sensitivity in detecting the influenza A virus is greater than in conventional test kits, and a determination of “positive” is obtained stably and with high precision at an earlier time during the onset of influenza symptoms. The present invention pertains to a kit for detecting influenza A virus, in which an antibody that is in solid phase in the chromatographic medium enters into an antigen-antibody reaction with native nuclear proteins of the influenza A virus, but in Western blots the antibody does not enter into antigen-antibody reactions with full-length nuclear proteins of the influenza A virus that have been separated using SDS-polyacrylamide gel electrophoresis.

Abstract: Chemiluminescent substances are prepared by freezing or lyophilizing a solution of a peroxidized nitrogen-containing five-membered cyclic compound. The chemiluminescent substances have a sensitivity comparable to that of luminol chemiluminescence, are highly water-soluble, have no incorporation of impurities, are not degraded during storage, have high reproducibility in measurement results, and are very suitable for use in the detection and quantification of various substances in many applications, e.g., clinical applications.

Abstract: The present invention provides a method and apparatus for measuring the membrane potential of red blood cells using electrophoretic analysis that analyzes red blood cells whose membrane potentials are reversed due to red blood cell agglutination.

Abstract: The present invention provides an organic monolith reactor and the preparation method thereof, wherein the reactor is possible to manufacture even into a small size and even at room temperature, and the manufacturing process is simple and relatively short period of time is required. In an organic monolith reactor according to the present invention, a horseradish peroxidase is embedded onto a microscopic area with a photopolymerized polymer. The method of preparing an organic monolith reactor according to the present invention comprises (a) dispersing a horseradish peroxidase in a mixed solution of a photopolymerizable monomer and a photopolymerizing agent, (b) introducing the dispersed solution into a microscopic area, and (c) performing a photo-irradiation onto the microscopic area at room temperature.

Abstract: A device for determining the distribution of glycation of erythrocytic membranes includes a container as a cell for electromagnetic-phoresis, a cathode ray and an anode ray which are connected to a direct current power supply, and a magnetic sheet which is placed outside the bottom of the container. The container has an upper surface containing a cathode hole, an anode hole, a filling hole midway between the cathode hole and the anode hole for a specimen, and an excretory hole for releasing air bubbles. After physiological saline is poured into the container, the cathode ray and the anode ray are respectively inserted into the holes to be soaked in the saline. Subsequently, a specimen of erythrocytes, which are bonded with the boric acid-magnetic beads, is infused into the container through the filling hole.
