Used in targeted cancer therapies, particularly for mesothelioma, ovarian, and pancreatic cancers that overexpress mesothelin. Binds specifically to mesothelin on cancer cells, enabling delivery of cytotoxic agents or facilitating immune-mediated destruction. Employed in the development of antibody-drug conjugates (ADCs), chimeric antigen receptor (CAR) T-cell therapies, and diagnostic imaging agents. Supports research into tumor targeting, immune activation, and therapeutic efficacy in preclinical models.
