    • A method for detecting a Norwalk-Like Virus (NLV) in a biological sample, comprising the steps of: obtaining a biological sample suspected of containing a NLV; contacting the biological sample with at least one human histo-blood group antigen to allow formation of a complex of the NLV with the antigen; and detecting the antigen NLV complex. The antigen-NLV complex can be detected by contacting the NLV-antigen complex with a NLV antibody that binds at an epitope of the NLV, and detecting the NLV antibody. The invention also includes a method for identifying compounds, and the compounds, that can inhibit the binding between a Norwalk-Like Virus (NLV) and a histo-blood group antigen. The method includes the steps of contacting the NLV target with a compound; subsequently contacting the NLV with a standard compound that is known to be bound at a determinant binding site of the NLV; and determining whether the binding of the standard compound is decreased in the presence of the test compound, the decrease in binding being an indication that the test compound inhibits the binding activity of the NLV with the standard compound. In preferred embodiments, the standard compound is a histo-blood group antigen.
    • 一种用于检测生物样品中诺沃克样病毒(NLV)的方法,包括以下步骤:获得怀疑含有NLV的生物样品; 使生物样品与至少一种人类组织血型抗原接触以允许形成NLV与抗原的复合物; 并检测抗原NLV复合物。 可以通过将NLV抗原复合物与结合NLV表位的NLV抗体接触并检测NLV抗体来检测抗原NLV复合物。 本发明还包括鉴定可抑制诺瓦克样病毒(NLV)与组织血型抗原之间的结合的化合物和化合物的方法。 该方法包括使NLV靶与化合物接触的步骤; 随后使NLV与已知结合于NLV的决定簇结合位点的标准化合物接触; 并确定在测试化合物存在下标准化合物的结合是否降低,结合的降低表明测试化合物抑制NLV与标准化合物的结合活性。 在优选的实施方案中,标准化合物是组织血型抗原。

    • The present invention provides matched antibody pairs for the specific detection of one or more of the four dengue virus serotypes in a biological sample that may contain one or more of such dengue virus serotypes. Each matched antibody pair is capable of detecting not more than one serotype of dengue virus NS1 protein that may be present in the sample and will not cross react with other serotypes that may be present in the sample. Multiple matched pairs may be used to detect one or more dengue virus serotypes that may be present in a sample. Such matched pair antibodies, facilitate the development of confirmatory in vitro diagnostic tests such as sandwich immunoassays, that detect and distinguish the presence of one or more dengue virus serotypes in a biological sample, preferably a sample derived from human subject. The invention also provides kits comprising the matched antibody pairs of the invention and methods for using the kits for immunoassays for the specific detection of one or more serotypes of dengue virus in a patient population. The present invention also provides monoclonal antibodies specific for the NS1 protein of dengue virus and therapeutic compositions and methods for treating dengue virus infection.
    • 本发明提供了用于对可能含有一种或多种登革病毒血清型的生物样品中的四种登革病毒血清型中的一种或多种进行特异性检测的匹配抗体对。 每个匹配的抗体对能够检测出样品中可能存在的登革热病毒NS1蛋白不超过一种血清型,并且不会与可能存在于样品中的其他血清型交叉反应。 多个匹配的对可以用于检测样品中可能存在的一种或多种登革病毒血清型。 这种匹配的抗体有助于开发验证性体外诊断测试,例如夹心免疫测定法,其检测和区分生物样品中一种或多种登革病毒血清型的存在,所述生物样品优选来源于人的样品 学科。 本发明还提供了包含本发明的匹配抗体对的试剂盒以及使用该试剂盒进行免疫测定以特异性检测患者群体中的一种或多种登革病毒血清型的方法。 本发明还提供了对登革热病毒NS1蛋白具有特异性的单克隆抗体,以及治疗登革热病毒感染的治疗组合物和方法。
