    • A lateral flow chromatographic assay format for the performance of rapid enzyme-driven assays is described. A combination of components necessary to elicit a specific enzyme reaction, which are either absent from the intended sample or insufficiently present therein to permit completion of the desired reaction, are predeposited as substrate in dry form together with ingredients necessary to produce a desired color upon occurrence of the desired reaction. The strip is equipped with a sample pad placed ahead of the substrate deposit in the flowstream, to which liquid sample is applied. The sample flows from the sample pad into the substrate zone where it immediately reconstitutes the dried ingredients while also intimately mixing with them and reacting with them at the fluid front. The fluid front moves rapidly into the final “read zone” wherein the color developed is read against predetermined color standards for the desired reaction. Pretreatment pads for the sample, as needed, are placed in front of the sample pad in the flow path as appropriate. The assay in the format of the invention is faster and easier to perform than analogous wet chemistry assays.
    • 描述了用于快速酶驱动测定的侧流色谱测定方法。 将引起特定酶反应(其不在预期样品中或不充分存在于其中以允许完成所需反应)所需的组分的组合预先沉积为干燥形式的底物以及在发生时产生所需颜色所需的成分 的所需反应。 带材上装有样品垫,放置在流动的衬底沉积物的前面,并向其施加液体样品。 样品从样品垫流入基底区域,在那里它立即重构干燥的成分,同时与它们充分混合并在流体前面与它们反应。 流体前沿快速移动到最终的“读取区域”,其中根据预期的颜色标准读取显色的颜色用于所需的反应。 根据需要将样品的预处理垫适当地放置在流路中的样品垫的前面。 本发明形式的测定比类似的湿化学测定更快更容易进行。
