    • A device is disclosed for conducting an assay method. The device comprises a housing, means enclosed in the housing for capturing a member of a specific binding pair in a zone and for allowing liquid to be transported by capillary action away from the zone, one or more self-contained liquid reagents enclosed in the housing for conducting an assay method for the determination of an analyte in the sample, and means in the housing for introducing the sample into the device. Preferably, the self-contained reagents are liquid reagents which are contained in a breakable container. The device of the invention finds use in assay methods for the determination of an analyte in a sample suspected of containing the analyte. Kits for conducting an assay method are also disclosed.

    • A method and device for determining the presence of an analyte in a sample suspected of containing the analyte is disclosed. The method involves contacting a test solution containing the sample and a first member of a specific binding pair with an end portion of a strip of bibulous material capable of being traversed by the test solution through capillary action. The first member of a specific binding pair is capable of binding the analyte. The strip contains a second member of a specific binding pair integral therewith for concentrating and non-diffusively binding the first sbp member at a small situs on the strip separated from the end portion of the strip. The detectible signal is produced in relation to the presence of the analyte in the test solution. The test solution passes through the situs as the test solution traverses the bibulous material. After the test solution has been allowed to traverse at least a portion of the strip, the strip is contacted with a developer solution containing members of a signal producing system in a manner that provides contact of the developer solution with the small situs following its contact with the test solution. The strip is then contacted with any remaining members of the signal producing system. The detectible signal produced at the situs is then compared with the signal detectible at a portion of the strip other than the situs to determine the analyte in the sample. In one embodiment of the invention the signal produced at the small situs has a sharp-edged distinctive pattern that provides a sharp contrast to the signal produced at adjacent sites on the strip when analyte is present in the test solution.
    • 公开了一种用于确定怀疑含有分析物的样品中分析物的存在的方法和装置。 该方法包括将含有样品和特定结合对的第一成员的测试溶液与能够通过毛细管作用穿过测试溶液的吸水材料条的端部接触。 特异性结合对的第一个成员能够结合分析物。 该带包含与其成一体的特定装订对的第二构件,用于在与带的端部分离的带上的小位置处浓缩和非扩散地结合第一sbp构件。 相对于测试溶液中分析物的存在产生可检测信号。 当测试溶液穿过吸水材料时,测试溶液通过位置。 在测试溶液被允许穿过条带的至少一部分之后,条带与含有信号产生系统的显影剂溶液的方式接触,该显影剂溶液以与显影剂溶液接触之后提供显影剂溶液与小部位的接触的方式 测试解决方案。 然后将条带与信号产生系统的任何剩余部件接触。 然后将在该位置处产生的可检测信号与除了位置之外的条带部分处可检测的信号进行比较,以确定样品中的分析物。 在本发明的一个实施例中,在小区域产生的信号具有尖锐的特征图案,当分析物存在于测试溶液中时,与带上的相邻位置产生的信号形成鲜明的对比。
