Detection of Human NAALADase-2/NAALAD2 by Western Blot. Western blot shows lysates of human testis tissue. PVDF membrane was probed with 0.5 µg/mL of Mouse Anti-Human NAALADase-2/NAALAD2 Monoclonal Antibody (Catalog # MAB7658) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for NAALADase-2/NAALAD2 at approximately 110 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

NAALADase-2/NAALAD2 in Human Testis. NAALADase-2/NAALAD2 was detected in immersion fixed paraffin-embedded sections of human testis using Mouse Anti-Human NAALADase-2/ NAALAD2 Monoclonal Antibody (Catalog # MAB7658) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to plasma membranes of spermatocytes. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Background: NAALADase-2/NAALAD2

N-acetylated-alpha-linked acidic dipeptidase 2 (NAALADase-2), also known as glutamate carboxypeptidase 3 (GCP3), is a 90-100 kDa type 2 transmembrane protein in the M28 peptidase family. It hydrolyzes beta-citrylglutamate (BCG) and N-acetyl-aspartylglutamate (NAAG) which are abundant dipeptides found in brain and testis. Mature human NAALADase-2 consists of a 7 amino acid (aa) cytoplasmic domain, a 24 aa transmembrane segment, and a 709 aa extracellular region (aa 32-740) that contains the peptidase domain. Over aa 32-740, human NAALADase-2 shares 89% aa sequence identity with mouse NAALADase-2.
