Nonstructural protein of hepatitis C virus, and diagnostic method and kit using the same.

摘要

The invention relates to DNA molecules, polypeptides expressed by them and their use in diagnosis and their methods of production. More particularly, it relates to a diagnostic DNA molecule, a diagnostic protein, diagnostic antibodies and protective antigen and antibodies for hepatitis C virus (HCV). The DNA molecule disclosed herein is characterized by the DNA molecule derived from the genome of an HCV, and coding for a polypeptide displaying the antigenicity of an HCV nonstructural protein. The polypeptide may be used in the detection of a hepatitis C virus.
