PSMA (Prostate-specific membrane antigen, Glutamate carboxypeptidase 2) is a membrane peptidase expressed in the prostate, central and peripheral nervous system, kidney, and small intestine (1). PSMA has both folate hydrolase and N-acetylated-alpha-linked-acidic dipeptidase
(NAALADase) activity. It is required in the intestine for the uptake of folate, and in the brain it modulates excitatory neurotransmission through the hydrolysis of the neuropeptide
N-acetylaspartylglutamate, thereby releasing glutamate (2). In the central nervous system, it is responsible for the cleavage of N-acetyl- L-aspartyl-L-glutamate yielding free glutamate in the synaptic cleft, and is implicated in various pathologic conditions associated with glutamate excitotoxicity (1). PSMA also has abundant and restricted expression on the surface of prostate carcinomas and the neovasculature of most other solid tumors, making it a target for cancer
Suitable for use in Western Blot and Immunocytochemistry. Other applications not tested.
Western Blot: 1:2000-1:5000
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
