To provide the following instruments 1 and 2 as a low-molecular-weight substance detection instrument employing immunochromatography capable of detecting conveniently and sensitively detecting a low-molecular weight substance such as an environmental pollutant (e.g., a dioxin), as a target substance contained in a test sample: 1. an instrument, which comprises 1) a test sample application section with which a test sample is brought into contact; 2) a label product reaction section containing a label product containing, as a portion thereof, an antibody capable of binding to a target substance contained in the test sample, the label product being not bound to the reaction section; 3) an unbound label product capturing section containing an element capable of capturing the label product which is not bound to the target substance, the element being bound to the capturing section; and 4) a detection section containing a detection element which, when coming into contact with the target substance bound to the label product, causes a visually observable change, and 2. an instrument wherein a test sample is reacted with a labeled antibody containing, as a portion thereof, an antibody capable of binding to a target substance contained in the test sample, and the resultant reaction product is employed for detecting the target substance contained in the test sample.
提供以下仪器1和2作为低分子量物质检测仪器,采用免疫层析技术,能够方便敏感地检测低分子量物质,例如环境污染物(例如二恶英),作为测试样品中包含的目标物质:1. 仪器,包括1)测试样品应用部分,用于将测试样品接触;2)标签产物反应部分,包含一种标签产物,其中包含一种能够结合到测试样品中的目标物质的抗体,标签产物未结合到反应部分;3)未结合标签产物捕获部分,包含一种能够捕获未结合到目标物质的标签产物的元素,该元素与捕获部分结合;以及4)检测部分,包含一种检测元素,当与结合到标签产物的目标物质接触时,会引起可视的变化;2. 仪器,其中测试样品与标记抗体反应,其中一部分包含能够结合到测试样品中的目标物质的抗体,产生的反应产物用于检测测试样品中包含的目标物质。
