PSMA-11 free base(CAT: I035163), also known as DKFZ-PSMA-11 or HBED-CC-PSMA, is a ligand used for gallium Ga 68-labeled PSMA-11, a radiotracer for PET imaging of PSMA-expressing tumors. PSMA-11 targets PSMA, a membrane protein expressed on prostatic epithelial and prostate tumor cells. Upon intravenous administration of the radiotracer, PSMA-expressing tumor cells can be detected during PET imaging. PSMA-11 enables the diagnosis, staging, and monitoring of prostate cancer due to its high specificity for PSMA-expressing cells.
