  • Method for detecting an infection by the hepatitis C virus
    Patent number: 10345305
    Abstract: The invention relates to a method of in-vitro detection of an infection with a hepatitis C virus (HCV) in a biological sample, comprising the simultaneous detection of the HCV capsid protein and of an antibody directed against said capsid protein, said method using, for capturing the anti-capsid antibodies, a peptide comprising an antigenic fragment derived from the truncated HCV capsid. The invention also relates to the peptide for capturing the anti-capsid antibodies and the kits comprising it.
