    • There is provided a lateral flow assay device for detecting the presence or quantity of an analyte residing in a test sample where the lateral flow assay device has a porous membrane in liquid communication with a conjugate pad and a wicking pad. The conjugate pad has a gold colloid-containing detection probe. The porous membrane has a detection zone where an immobilized first capture reagent configured to bind to at least a portion of the analyte and analyte-conjugate complexes to generate a detection signal. The control zone is located downstream from the detection zone on the porous membrane and has a second capture reagent immobilized within the control zone. The conjugate pad is located upstream from the detection zone, and has detection probes with specific binding members for the analyte. A sample containing an analyte is deposited on the conjugate pad, interacts with the detection probes, and moves toward the control zone for detection.
    • 提供了一种侧流测定装置,用于检测驻留在测试样品中的分析物的存在或数量,其中侧流测定装置具有与结合垫和芯吸垫液体连通的多孔膜。 共轭垫具有含金胶体的检测探针。 多孔膜具有检测区,其中固定的第一捕获试剂被配置为结合至少一部分分析物和分析物 - 共轭复合物以产生检测信号。 控制区位于多孔膜上的检测区的下游,并且具有固定在控制区内的第二捕获试剂。 缀合垫位于检测区的上游,并具有用于分析物的具有特异性结合构件的检测探针。 将含有分析物的样品沉积在共轭垫上,与检测探针相互作用,并朝向控制区移动进行检测。
