Anti-PSMA/FOLH1 Antibody, clone 3F11

Glutamate carboxypeptidase 2 (UniProt: Q04609; also known as EC:3.4.17.21, Cell growth-inhibiting gene 27 protein, Folate hydrolase 1, Folylpoly-gamma-glutamate carboxypeptidase, FGCP, Glutamate carboxypeptidase II, GCPII, Membrane glutamate carboxypeptidase, mGCP, N-acetylated-alpha-linked acidic dipeptidase I, NAALADase I, Prostate-specific membrane antigen, PSM, PSMA, Pteroylpoly-gamma-glutamate carboxypeptidase) is encoded by the FOLH1 (also known as FOLH, NAALADI, PSM, PSMA, GIG27) gene (Gene ID: 2346) in human. PSMA is a single-pass type II membrane protein that has both folate hydrolase and N-acetylated-alpha-linked-acidic dipeptidase activities. It exhibits a preference for tri-alpha-glutamate peptides. Its expression pattern is restricted mainly to the healthy prostate secretory-acinar epithelium and the plasma membrane of epithelial prostate carcinoma. In the brain, it modulates excitatory neurotransmission through the hydrolysis of the neuropeptide, N-aceylaspartylglutamate (NAAG) and release of glutamate. Clone 3F11 is shown to be highly specific for PSMA and does not exhibit any cross-reactivity with unrelated proteins. It binds to a linear epitope (aa 226-243) within the extracellular domain and is reported to be suitable for the detection of PSMA orthologs from some other species when denatured form of PSMA is used.

Clone 3F11 is a mouse monoclonal antibody that detects Prostate-specific membrane antigen (PSMA). It targets an epitope within 18 amino acids from the extracellular domain.

Full-length recombinant human Prostate-specific membrane antigen (PSMA).
