Prostate-specific membrane antigen (PSMA) is a type II transmembrane glycoprotein that
consists of 750 amino acids. It is highly expressed on most prostate cancer cells and
neovascular endothelial cells of tumors, making PSMA a highly specific and significant
imaging target for malignancies.
[68Ga]P3, a novel molecular probe of PET imaging agent that targets PSMA, can be used in the
diagnosis and research of a wide variety of PSMA high-expression malignanciesr.
