  • General notes

    ab64082 was switched from a hybridoma to recombinant production method on 17th September 2019.

    Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

    This product is a recombinant monoclonal antibody, which offers several advantages including:

    • High batch-to-batch consistency and reproducibility
    • Improved sensitivity and specificity
    • Long-term security of supply
    • Animal-free production

Properties

Applications

Our Abpromise guarantee covers the use of ab64082 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P 1/100. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
1/100 for 30 min at room temperature. Staining of formalin fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0 for 10 min followed by cooling at room temperature for 20 min.

Target

  • Function

    Has both folate hydrolase and N-acetylated-alpha-linked-acidic dipeptidase (NAALADase) activity. Has a preference for tri-alpha-glutamate peptides. In the intestine, required for the uptake of folate. In the brain, modulates excitatory neurotransmission through the hydrolysis of the neuropeptide, N-aceylaspartylglutamate (NAAG), thereby releasing glutamate. Isoform PSM-4 and isoform PSM-5 would appear to be physiologically irrelevant. Involved in prostate tumor progression.
    Also exhibits a dipeptidyl-peptidase IV type activity. In vitro, cleaves Gly-Pro-AMC.
  • Tissue specificity

    Highly expressed in prostate epithelium. Detected in urinary bladder, kidney, testis, ovary, fallopian tube, breast, adrenal gland, liver, esophagus, stomach, small intestine, colon and brain (at protein level). Detected in the small intestine, brain, kidney, liver, spleen, colon, trachea, spinal cord and the capillary endothelium of a variety of tumors. Expressed specifically in jejunum brush border membranes. In the brain, highly expressed in the ventral striatum and brain stem. Also expressed in fetal liver and kidney. Isoform PSMA' is the most abundant form in normal prostate. Isoform PSMA-1 is the most abundant form in primary prostate tumors. Isoform PSMA-2 is also found in normal prostate as well as in brain and liver. Isoform PSMA-9 is specifically expressed in prostate cancer.
  • Sequence similarities

    Belongs to the peptidase M28 family. M28B subfamily.
  • Domain

    The NAALADase activity is found in the central region, the dipeptidyl peptidase IV type activity in the C-terminal.
  • Post-translational
    modifications

    The first two amino acids at the N-terminus of isoform PSMA' appear to be cleaved by limited proteolysis.
    The N-terminus is blocked.
  • Cellular localization

    Cytoplasm and Cell membrane.
