Ancillary Reagent Kit Available
DY008, DuoSet ELISA Ancillary Reagent Kit 2 -
This DuoSet ELISA Development kit contains the basic components required for the development of sandwich ELISAs to measure natural and recombinant human Prostate-Specific Membrane Antigen (PSMA). The suggested diluent is suitable for the analysis of most cell culture supernate, cell lysate, serum, and plasma samples. Diluents for complex matrices, such as cell lysates, serum, and plasma, should be evaluated prior to use in this DuoSet.

Background: PSMA/FOLH1/NAALADase I
Human prostate-specific membrane antigen (PSMA), a tumor marker in prostate cancer encoded by the FOLH1 gene, is a type II transmembrane zinc metallopeptidase. PSMA is most highly expressed in the nervous system, prostate, kidney, and small intestine. The enzyme is also known as glutamate carboxypeptidase II (GCPII), folate hydrolase 1, folypoly-gamma-glutamate carboxypeptidase (FGCP), and N-acetylated-alpha-linked acidic dipeptidase I (NAALADase I).
In the brain, PSMA hydrolyzes the neurotransmitter N-acetyl-Asp-Glu to produce glutamate, another neurotransmitter. Inhibition of brain PSMA activity is considered to be a promising approach for the treatment of neurological disorders associated with glutamate excitotoxicity, such as stroke, chronic pain, and amyotrophic lateral sclerosis. Intestinal PSMA hydrolyzes folylpoly-gamma-glutamates, facilitating the uptake of folate.
