IMMUNOASSAY FOR HEPATITIS B VIRUS CORE-RELATED ANTIGEN AND KIT THEREFOR

摘要

Disclosed is a novel immunoassay method that has a greater sensitivity in detecting hepatitis B virus genotype D than conventional methods. This immunoassay method for hepatitis B virus core-related antigen uses, as an antibody used in the immunoassay, a monoclonal antibody that specifically binds to at least one type of hepatitis B virus genotype D core-related antigen, or an antigen-binding fragment thereof, wherein a region included in the amino acid sequence from position 31 to position 48 in SEQ ID NO: 3 serves as an epitope.
