This invention discloses a competitive
monoclonal antibody against bovine ephemeral fever
virus (BOF) and its application in constructing a competitive
ELISA kit, belonging to the field of
monoclonal antibody technology. The technical problem this invention aims to solve is how to accurately detect BEF. This invention provides a competitive
monoclonal antibody against BEF, wherein the
amino acid sequence of the
heavy chain variable region of the
monoclonal antibody is shown in SEQ ID NO.2; and the
amino acid sequence of the light chain variable region of the
monoclonal antibody is shown in SEQ ID NO.7. This enables rapid and accurate diagnosis of BEF, facilitating timely implementation of prevention and control measures and reducing the risk of epidemic transmission.
