Used in research and therapeutic development targeting hepatocyte growth factor activator (HGFA), this antibody serves as a reference tool to inhibit HGFA activity. It is applied in studies related to tissue regeneration, cancer progression, and fibrosis, where HGFA-mediated activation of HGF/Met signaling plays a critical role. The antibody helps characterize the function of HGFA in disease models and supports the development and validation of new anti-fibrotic or anti-cancer agents. It is also employed in assay calibration and as a benchmark in antibody drug discovery efforts.
