HCV Recombinant Antigen and Mutant thereof

Abstract

The application relates to an HCV recombinant antigen and a mutant thereof. The application provides an HCV recombinant antigen, the HCV recombinant antigen including at least 1 NS3 antigen, wherein at least one cysteine of the NS3 antigen in positions 1192-1517 of an HCV amino acid sequence is mutated into G and/or A, and preferably mutated into A. The application further provides a nucleic acid encoding the HCV recombinant antigen, an expression vector including the nucleic acid, a host cell including the expression vector, a conjugate including the HCV recombinant antigen, and a kit including the HCV recombinant antigen.
