Abstract: A method of assaying a sample with the use of the aggregation reaction of immunological microparticles and an assay kit. The assay is conducted by using microparticles wherein the same or an analog of the analyte and a substance that specifically binds to a substance that can specifically bind to the analyte are both bound to an insoluble carrier. Thus, it becomes possible to conveniently carry out the assay even in the case where the analyte has only a small number of specific binding sites, without especially adding a competitive substance carrying hapten bonded thereto to the reaction system so as to induce simultaneous competition of the target substance and the competitive substance.

Abstract: A reagent kit for determining an analyte in a sample by agglutination includes a first reagent containing a first specific binding substance that is a substance that can specifically bind to the analyte; and a second reagent containing microparticles having a second specific binding substance bound thereto, the second specific binding substance being a monoclonal antibody against the first specific binding substance.

Abstract: A method for determining an analyte in a sample, includes the steps of: (a) mixing the analyte and a first specific binding substance, the first specific binding substance being a substance that can specifically bind to the analyte; (b) adding microparticles having a second specific binding substance bound thereto to a mixture obtained in the step (a) and mixing therewith, the second specific binding substance being a substance that can specifically bind to the first specific binding substance; and (c) determining an agglutination reaction of the microparticles in a mixture obtained in the step (b).

Abstract: A method for measuring an analyte in a sample, includes the steps of (a) mixing a sample containing the analyte, a complex comprising a plurality of molecules of a substance that specifically binds to the analyte, and microparticles each having the analyte or an analog of the analyte bound to an insoluble support; and (b) measuring an agglutination reaction of the microparticles in a mixture obtained in the step (a). In the method, for example, an antibody is used in the form of a complex of a plurality of molecules of the antibody, rather than in the form of a single molecule of the antibody. Therefore, the sensitivity to the measurement is increased, and the measurement in a lower concentration range becomes possible. A reagent kit for measuring is also disclosed.

Abstract: A packing buffer member of the present invention is a packing buffer member 200 or 300 that is to be placed inside a pack 400 with an object to be packed 100, and includes first hollow convex parts 210, 220, 230 and 240 (third hollow convex parts 310, 320, 330 and 340) that are formed in a first direction relative to a forming base surface 201 or 301 and that contact with the object to be packed 100 to hold the object to be packed 100 and second hollow convex parts 250, 260, 270 and 280 (the fourth hollow convex parts 350, 360, 370 and 380) that are formed in a second direction opposite to the first direction relative to the forming base surface 201 or 301 and that contact inside the pack. The packing buffer member 200 or 300 is formed by a plastic sheet.

Abstract: Provided is a method for maintaining the reactivity of microparticles having a reactive substance bound thereto in a dispersion liquid of the microparticles over a long period of time by stabilizing the microparticles in the dispersion liquid. The method for stabilizing microparticles having a reactive substance bound thereto includes the step of allowing a sulfur-containing amino acid or a derivative thereof to coexist in a dispersion liquid of the microparticles. The sulfur-containing amino acid includes one or more of cysteine, cystine, and methionine. The method is particularly useful when a precipitation preventing substance, such as a polyanion, dextran, or the like, is allowed to coexist in the dispersion liquid.

Abstract: A method for measuring an acrolein adduct present in a sample comprising the steps of: (a) mixing a sample containing the acrolein adduct with a solution comprising an immunoglobulin that specifically recognizes the acrolein adduct; (b) adding to the mixture obtained in the step (a), a solution comprising microparticles to which a substance that specifically binds to the immunoglobulin that specifically recognizes the acrolein adduct and a blocking agent have been bound, and mixing them; and (c) measuring an extent of an agglutination reaction of the microparticles in the mixture obtained in the step (b), wherein the extent of the agglutination reaction being decreased relative to an amount of the acrolein adduct in the sample. The method enables a measurement of an acrolein adduct without requiring a complex operation.

Abstract: A method of carrying rats and an apparatus for trapping rats capable of solving problems of a prior art apparatus by repeatedly using a single carrier during the carriage of a rat. In the course of carrying a rat inside a duct toward a processing site, air flow is generated to move a carrier which pushes and moves the rat to the processing site but the carrier is held so as to be returned to its original position. At this time, another air flow is generate to return the carrier to its original position to prepare for a next trapping operation.
