Aminopeptidase N/CD13 Antibody [Unconjugated]

Simple Western lane view shows lysates of human small intestine tissue and human prostate tissue, loaded at 0.5 mg/mL. A specific band was detected for Aminopeptidase N/CD13 at approximately 177-198 kDa (as indicated) using 10 µg/mL of Sheep Anti-Human Aminopeptidase N/CD13 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3815) followed by 1:50 dilution of HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

U937 human histiocytic lymphoma cell line was stained with Sheep Anti-Human Aminopeptidase N/CD13 Antigen Affinity‑purified Polyclonal Antibody (Catalog # AF3815, filled histogram) or isotype control antibody (Catalog # 5-001-A, open histogram), followed by APC-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # F0127).

Western blot shows lysates of human kidney tissue and human prostate tissue. PVDF membrane was probed with 0.5 µg/mL of Sheep Anti-Human Aminopeptidase N/CD13 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3815) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Aminopeptidase N/CD13 at approximately 150 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Aminopeptidase N/CD13 was detected in immersion fixed paraffin-embedded sections of human kidney using Sheep Anti-Human Aminopeptidase N/CD13 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3815) at 0.3 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific staining was localized to convoluted tubules.

Background

The human ANPEP gene encodes aminopeptidase N (APN), which is also known as microsomal aminopeptiase, alanyl aminopeptidase, aminopeptidase M, CD13, or membrane protein p161 (1‑3). The deduced amino acid sequence of human APN consists of a short cytoplasmic tail (residues 2 to 8), a transmembrane region (residue 9 to 32), a Ser/Thr rich region and a zinc metalloprotease domain (residues 69 to 966). Widely expressed in many cells, tissues and species, APN cleaves the N-terminal amino acids from bioactive peptides, leading to their inactivation or degradation. The roles of APN in many fields, such as neuroscience, hematopoeitic cells, immune system, angiogenesis, cancer and viral infection, have been reviewed (3).
