PSMA Detection Service

Creative BioMart Biomarker provides customers with prostate-specific membrane antigen (PSMA) immunohistochemical analysis services. Customers only need to provide tissue samples (the primary antibodies used can be provided by the customer or by us), and we will return detailed experimental data, pictures and reports. Our services are only used for research purposes and not for clinical diagnosis.

Assay Background

PSMA is a type II membrane glycoprotein, composed of intracellular domain, transmembrane domain and extracellular domain. PSMA has unique folate hydrolase and neurocarboxypeptidase activities. PSMA is expressed in tissues such as prostate, small intestine, salivary glands, and proximal renal tubules, and the expression level in prostate is higher than other tissues. PSMA is a well-established and highly specific prostate epithelial cell membrane antigen, which is highly expressed in almost all prostate cancers. Its expression level is correlated with tumor aggressiveness, disease recurrence and metastatic disease. Therefore, PSMA is considered as a specific biomarker of prostate cancer, which has research significance in the progression of prostate cancer and is also an ideal target for prostate cancer imaging and treatment. In addition, PSMA is not expressed in the normal vascular system, but is expressed in the neovascular system of solid tumors (such as pancreatic cancer, kidney cancer, lung cancer and bladder cancer), so it is also considered to be the target of these tumor treatment research.
