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).
本公开提供了使用 NS3 捕获肽检测样本中的受试者抗-HCV 抗体的方法、试剂盒和组合物。在某些实施方案中,至少两种 NS3 螺旋酶(NS3h)捕获肽和至少两种共轭肽(如 NS3h 共轭肽)一起使用,这样就能在一步式检测中检测出广泛的受试者抗体动态范围。在其他实施方案中,提供了不使用还原剂检测 NS3 特异性受试者抗体的方法。在某些实施方案中,NS3 特异性抗体的检测采用 NS3 结合肽的 "双击"(例如,在洗涤前和洗涤后将结合肽添加到样品中)。
