Used in research and diagnostic applications targeting prostate-specific membrane antigen (PSMA), a key biomarker for prostate cancer. Enables detection, quantification, and imaging of PSMA expression in tissue samples and live cells. Supports development of targeted therapies, including radiolabeled compounds and antibody-drug conjugates. The His Tag facilitates purification and detection in immunoassays and protein interaction studies. Plays a role in advancing precision medicine for prostate cancer diagnosis and treatment monitoring.
