Scientific Data Images for Human PSMA/FOLH1/NAALADase I Antibody

Detection of Human PSMA/FOLH1/ NAALADase I antibody by Western Blot.

Detection of Human PSMA/FOLH1/ NAALADase I by Western Blot.

Western blot shows lysates of human prostate tissue. PVDF membrane was probed with 0.2 µg/mL of Sheep Anti-Human PSMA/FOLH1/ NAALADase I Antigen Affinity-purified Poly-clonal Antibody (Catalog # AF4234) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for PSMA/FOLH1/NAALADase I at approximately 120 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of PSMA/FOLH1/ NAALADase I antibody in LnCAP Human Cell Line antibody by Flow Cytometry.

Detection of PSMA/FOLH1/ NAALADase I in LnCAP Human Cell Line by Flow Cytometry.

LnCAP human prostate cancer cell line was stained with Human PSMA/FOLH1/NAALADase I Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4234, filled histo-gram) or control antibody (Catalog # 5-001-A, open histo-gram), followed by Northern-Lights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # NL010).
PSMA/FOLH1/NAALADase I antibody in Human Prostate Cancer Tissue by Immunohistochemistry (IHC-P).

PSMA/FOLH1/NAALADase I in Human Prostate Cancer Tissue.

PSMA/FOLH1/NAALADase I was detected in immersion fixed paraffin-embedded sections of human prostate cancer tissue using Sheep Anti-Human PSMA/FOLH1/NAALADase I Antigen Affinity-purified Poly-clonal Antibody (Catalog # AF4234) at 5 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counter-stained with hematoxylin (blue). Specific labeling was localized to the plasma membrane and extracellular space. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Applications for Human PSMA/FOLH1/NAALADase I Antibody

Application
Recommended Usage

CyTOF-ready

Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

ELISA

This antibody functions as an ELISA detection antibody when paired with Mouse Anti-Human PSMA/FOLH1/NAALADase I Monoclonal Antibody (Catalog # MAB42341).

This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Human PSMA/FOLH1 DuoSet ELISA Kit (Catalog # DY4234-05) for convenient development of a sandwich ELISA.

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 that is most highly expressed in the nervous system, prostate, kidney, and small intestine (1, 2). 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 (3). Intestinal PSMA hydrolyzes folylpoly-gamma -glutamates, facilitating the uptake of folate (4).
