    Abstract: The present disclosure provides methods, kits, and compositions for detecting subject anti-HCV antibodies in a sample using NS3 capture peptides. In certain embodiments, at least two NS3 helicase (NS3h) capture peptides and at least two conjugate peptides (e.g., NS3h conjugate peptides) are employed together, which allows for a broad dynamic range of subject antibody detection in a one-step type assay. In other embodiments, methods are provided of detecting NS3-specific subject antibodies without the use of a reducing agent. In some embodiments, NS3-specific subject antibodies are detected with a 'double shot' of NS3 conjugate peptide (e.g., conjugate peptide added to a sample both before and after washing).

    Abstract translation: 本公开提供了使用NS3捕获肽检测样品中的受试者抗HCV抗体的方法,试剂盒和组合物。 在某些实施方案中,一起使用至少两种NS3解旋酶(NS3h)捕获肽和至少两种缀合肽(例如NS3h缀合肽),其允许在一步式测定中的主题抗体检测的宽动态范围。 在其它实施方案中,提供了在不使用还原剂的情况下检测NS3特异性目标抗体的方法。 在一些实施方案中,NS3特异性目标抗体用NS3缀合肽“双重”检测(例如,在洗涤前后添加到样品中的结合肽)。
