    • A device and method for the rapid on-site detection of inhibitors of enzymes, such as acetylcholinesterase, is described wherein the device contains all reagents added to a sample pad containing dried releasable enzyme creating a reaction mixture wherein inhibitor deactivates the enzyme, while said reaction mixture travels via a longitudinal membrane to a distal porous pad containing a substrate for the enzyme. The reaction of the enzyme and the substrate results in a product that can generate a measurable signal such as color, fluorescence or luminescence to serve as a reporter. Signal that is generated at this reaction zone is inversely proportional to inhibitor concentration in the test sample. A device containing two such strips, one for a test sample, the other for a negative control fluid as an onboard comparator is described. A purpose-built reader or an illuminating device, such as, containing an incandescent light source, a diode, a UV light source or any other illumination source that is suitable for the reporter or mere visualization is used to determine the level of reporter.
    • 描述了用于快速现场检测酶抑制剂如乙酰胆碱酯酶的装置和方法,其中装置包含添加到含有干燥的可释放酶的样品垫中的所有试剂,产生其中抑制剂使酶失活的反应混合物,而所述反应 混合物通过纵向膜移动到包含酶的底物的远端多孔垫。 酶和底物的反应产生可产生诸如颜色,荧光或发光之类的可测信号作为报道者的产物。 在该反应区产生的信号与测试样品中的抑制剂浓度成反比。 描述了包含两个这样的条的装置,一个用于测试样品,另一个用于作为板载比较器的负控制流体。 使用专门的读取器或照明装置,例如包含白炽灯光源,二极管,UV光源或适用于报告人或仅仅可视化的任何其他照明源,以确定报告者的水平。
