  • Patent number: 11340230
    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).
