Used in targeted cancer therapies, particularly for prostate cancer, due to its high specificity for PSMA (prostate-specific membrane antigen) expressed on prostate tumor cells. Enables precise delivery of therapeutic agents or imaging molecules, enhancing treatment efficacy and diagnostic accuracy. Also utilized in immunoassays and flow cytometry for detection and quantification of PSMA in research and clinical settings. Supports development of antibody-drug conjugates and radiolabeled antibodies for advanced oncology applications.
