Development of monoclonal antibodies for ASFV K205R protein and precise mapping of linear antigenic epitopes.

African swine fever virus (ASFV) is a complex DNA virus belonging to the family Asfarviridae. The outbreak of African swine fever (ASF) has caused huge economic losses to the pig farming industry. The K205R protein is a key target for detecting ASFV antibodies and represents an important antigen for early serologic diagnosis.
