Anti-PSMA antibody, Mouse monoclonal，100UL，SAB4200257-100UL，Sigma

General description

Monoclonal Anti-PSMA (mouse IgG1 isotype) is derived from the hybridoma 107-1A4 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice. Prostate-specific membrane antigen (PSMA) is an integral, non-shed, type 2 transmembrane glycoprotein belonging to the M28 peptidase family.
Prostate-specific membrane antigen (PSMA), also known as glutamate carboxypeptidase II (GCPII), folate hydrolase 1 (FOLH1), is a 100kDa membrane glycoprotein, composed of 750 amino acids. PSMA gene with 19 exons and 18 introns is mapped to human chromosome 11p11–12. The encoded protein is detected in various type of tissues including kidney, prostate and brain. PSMA contains short cytoplasmic amino terminus, a single membrane-spanning domain and a large extracellular domain.

Immunogen

prostate cancer LNCaP cells.

Application

Monoclonal Anti-PSMA antibody produced in mouse has been used in:

• enzyme linked immuno sorbent assay (ELISA)
• immunocytochemistry
• immunoprecipitation
• flow cytometry

Biochem/physiol Actions

Prostate-specific membrane antigen (PSMA), expressed in the brain, catalyzes the hydrolysis of N-acetyl-aspartyl glutamate to produce free glutamate. Elevated expression of the protein is associated with the development of prostate tumor. Mutations in PSMA leads to hyperhomocysteinemia. PSMA functions as a potential biomarker of prostate adenocarcinoma.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
