General description

Prostate-specific membrane antigen (PSMA), also known as Glutamate carboxypeptidase II (GCPII), Folate hydrolase 1 (FOLH1), and N-acetylated-alpha-linked acidic dipeptidase I (NAALADase I), is a member of the peptidase M28 family and is involved in prostate tumor progression. It is highly expressed in prostate epithelium and detected in urinary bladder, kidney, testis, ovary, fallopian tube, breast, adrenal gland, liver, esophagus, stomach, small intestine, colon, and brain (at protein level). Mutations in PSMA have been associated with prostate cancer and hyperhomocysteinemia. PSMA may be a possible marker for neurological disorders such as schizophrenia, Alzheimer′s disease, and Huntington disease.


Recombinant protein corresponding to human PSMA.


Anti-PSMA Antibody, clone 3/A12 is a highly specific mouse monoclonal antibody, that targets PSMA & has been tested in Flow Cytometry, western blotting, Immunofluorescence, Activity Assay & Inhibition.

Western Blotting Analysis: A representative lot from an independent laboratory detected purified PSMA in WB (Elsasser-Beile, U., et al. (2006). Prostate. 66(13):1359-1370.).

Immunofluorescence Analysis: A representative lot from an independent laboratory detected PSMA in LNCaP cells (Elsasser-Beile, U., et al. (2006). Prostate. 66(13):1359-1370.).

Inhibition Assay Analysis (Small-animal PET imaging): A representative lot from an independent laboratory blocked PSMA in mice bearing PSMA-positive C4-2 tumors and negative DU145 tumors (Elsasser-Beile, U., et al. (2009). J Nucl Med. 50(4):606-611.).

Activity Assay Analysis: A representative lot from an independent laboratory was co-internalized with cell adherent PSMA, when PSMA binds to its putative ligand (Liu, J. et al. (2009). Mol Pharm. 6(3):959-970.).
