The H171R protein, a structural component of ASFV, plays crucial roles in viral assembly, host cell entry, and modulation of the host immune response. This study aimed to comprehensively characterize the linear B-cell epitopes on the H171R protein to facilitate the development of diagnostic tools and subunit vaccines against ASFV. A combined approach involving bioinformatics analysis and experimental techniques was employed. The recombinant H171R protein was expressed and purified, and specific monoclonal antibodies were generated through immunization and hybridoma technology. Systematic epitope mapping using overlapping peptide fragments and alanine-scanning mutagenesis revealed four minimal linear epitopes:\n              <jats:sup>84<\/jats:sup>\n              HPLLPYQQSSDEQP\n              <jats:sup>97<\/jats:sup>\n              ,\n              <jats:sup>93<\/jats:sup>\n              SDEQPMMPYQQPPG\n              <jats:sup>106<\/jats:sup>\n              ,\n              <jats:sup>111<\/jats:sup>\n              PYEQIYHKKHASQQ\n              <jats:sup>124<\/jats:sup>\n              , and\n              <jats:sup>129<\/jats:sup>\n              LNDYYQHILALGDED\n              <jats:sup>143<\/jats:sup>\n              . The identified epitopes exhibited strong immunogenicity, as demonstrated by their reactivity with ASFV-positive swine sera. Critical amino acid residues within each epitope were identified through mutational analysis. Structural modeling and visualization of the H171R protein provided insights into the spatial distribution and accessibility of the epitope regions. These findings contribute to a better understanding of the H171R protein\u2019s antigenic properties and lay the foundation for developing effective diagnostic assays and subunit vaccines against African swine fever.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>IMPORTANCE<\/jats:title>\n            <jats:p>African swine fever virus (ASFV) poses a severe threat to the global swine industry.
