    • The present invention relates to a method of detection of a compound of interest that is present at low levels in a sample. In particular, the present invention relates to a method of detection of a compound of interest in solution by a nucleic acid-labelled binding construct, separation of the unbound nucleic acid-labelled binding construct, and the detection of the bound nucleic acid-labelled binding construct in the solution phase. The present invention is particularly adaptable to be used in conjunction with a nucleic acid amplification reaction for detecting the presence or absence of the nucleic acid portion of binding construct in a sample indicating the presence or absence of the compound of interest.
    • 本发明涉及在样本中以低水平存在的目标化合物的检测方法。 特别地,本发明涉及通过核酸标记的结合构建体检测溶液中感兴趣的化合物的方法,分离未结合的核酸标记的结合构建体以及检测结合的核酸标记的结合 在溶液相中构建。 本发明特别适合与核酸扩增反应结合使用,用于检测在表明存在或不存在感兴趣化合物的样品中结合构建体的核酸部分的存在或不存在。

    • A method of analyzing a sample for one or more analytes of interest includes: providing an element having a base layer; a layer containing streptavidin; a spreading layer, wherein the streptavidin may or may not be in the spreading layer; providing immunocomponents and labeled immunoreactants which may be in the spreading layer or may be combined with the sample; dispensing the sample, and optionally the immunocomponents and a labeled immunoreactant onto the spreading layer at three or more areas, wherein each center of the three or more areas is substantially equidistance to the center formed by the three or more areas, and wherein each area contacts an adjacent area such that wash fluid flow in any direction will contact sample; washing the sample and label by directing the wash fluid at the center formed by the three or more areas, whereby the wash fluid equally flows over each of the three or more areas; and taking a measurement at each three or more areas to determine the presence or concentration of the one or more analyte. In a preferred embodiment, the element is a dry slide used on a diagnostic analyzer.
    • 分析一种或多种感兴趣分析物的样品的方法包括:提供具有基础层的元件; 含有链霉亲和素的层; 扩散层,其中所述链霉抗生物素蛋白可以或不在扩散层中; 提供可以在扩散层中或可以与样品组合的免疫组分和标记的免疫反应物; 将样品和任选地将免疫组分和标记的免疫反应物分配到三个或更多个区域的扩散层上,其中三个或更多个区域的每个中心与由三个或更多个区域形成的中心基本上等距,并且其中每个区域接触 相邻区域使得洗涤流体沿任何方向流动将接触样品; 通过将清洗流体引导到由三个或更多个区域形成的中心处洗涤样品和标签,由此洗涤流体均匀地流过三个或更多个区域中的每一个; 并且在每个三个或更多个区域进行测量以确定一种或多种分析物的存在或浓度。 在优选实施例中,该元件是用于诊断分析器的干滑片。
