    • An immunoassay method comprising bringing an immobilized phase comprising, at different positions on a water-absorbable base material, at least two first immunity substances capable of specifically binding with at least two kinds of assay target substances selected from the group consisting of verotoxin-producing Escherichia coli, verotoxin and human hemoglobin contained in a test sample, into contact with a test sample and a liquid containing labeled immunity substances each comprising a second immunity substance that is labeled with colored particles and capable of binding with said assay target substance, thereby to form an assay target substance-labeled immunity substance complex and to bind said complex with respective first immunity substances at the immobilized phase. The immunoassay method, the immunoassay device and the immunoassay kit of the present invention enable easy and simultaneous analysis of O157 (VTEC), VT and Hb in a test sample, by adsorption of the assay target substances on an immobilized phase and evaluation of the developed color.
    • 一种免疫测定方法,其特征在于,使含有能够吸水性基材的不同位置的固定相含有至少两种能够与选自产生毒力素的大肠杆菌的至少两种检测对象物质特异性结合的第一免疫物质 包含在测试样品中的大肠杆菌,藜芦毒素和人血红蛋白与测试样品和含有标记免疫物质的液体接触,每个液体包含用有色颗粒标记并能够与所述测定目标物质结合的第二免疫物质,从而形成 测定目标物质标记的免疫物质复合物,并在固定化阶段将所述复合物与各自的第一免疫物质结合。 本发明的免疫测定方法,免疫测定装置和免疫测定试剂盒能够容易地并同时分析试验样品中的O157(VTEC),VT和Hb,通过将测定目标物质吸附在固定相上, 颜色。
