  • FunctionBroad specificity aminopeptidase. Plays a role in the final digestion of peptides generated from hydrolysis of proteins by gastric and pancreatic proteases. May play a critical role in the pathogenesis of cholesterol gallstone disease. May be involved in the metabolism of regulatory peptides of diverse cell types including small intestinal and tubular epithelial cells, macrophages, granulocytes and synaptic membranes from the CNS. Found to cleave antigen peptides bound to major histocompatibility complex class II molecules of presenting cells and to degrade neurotransmitters at synaptic junctions. Is also implicated as a regulator of IL-8 bioavailability in the endometrium, and therefore may contribute to the regulation of angiogenesis. Is used as a marker for acute myeloid leukemia and plays a role in tumor invasion. In case of human coronavirus 229E (HCoV-229E) infection, serves as receptor for HCoV-229E spike glycoprotein. Mediates as well human cytomegalovirus (HCMV) infection.
  • Tissue specificityExpressed in epithelial cells of the kidney, intestine, and respiratory tract; granulocytes, monocytes, fibroblasts, endothelial cells, cerebral pericytes at the blood-brain barrier, synaptic membranes of cells in the CNS. Also expressed in endometrial stromal cells, but not in the endometrial glandular cells. Found in the vasculature of tissues that undergo angiogenesis and in malignant gliomas and lymph node metastases from multiple tumor types but not in blood vessels of normal tissues. A soluble form has been found in plasma. It is found to be elevated in plasma and effusions of cancer patients.
  • Sequence similaritiesBelongs to the peptidase M1 family.
  • DomainAmino acids 260-353 are essential to mediate susceptibility to infection with HCoV-229E (in porcine/human chimeric studies) and more specifically amino acids 288-295 (mutagenesis studies).
  • Post-translational
    N- and O-glycosylated.
    May undergo proteolysis and give rise to a soluble form.
  • Cellular localizationCell membrane. Cytoplasm > cytosol. A soluble form has also been detected.

  • ab7417 staining CD13 in Human brain tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 1% serum for 20 minutes; antigen retrieval was by heat mediation in a citrate buffer. Samples were incubated with primary antibody (1/400) for 18 hours at 20°C. An undiluted HRP-conjugated Horse anti-mouse IgG polyclonal was used as the secondary antibody.

Thank you for your reply.
I cannot recommend this antibody for your purposes. Rat still shows a 77% homology and I am afraid that this could be boarder line and this antibody might cross-react.
It is always very difficult to positively proof ...

Thank you very much for your interest in ab7417.

To our knowledge, ab7417 has not been tested in on bovine samples, but based on sequence homology (there is a 87% level of homology between human and bovine), there is a high chance that this ...

Thank you for your enquiry. The best choice for a lysate would be a membrane fraction lysate, not a nuclear lysate, since CD13 is a trans-membrane protein. The antigen is expressed on a variety of tissues. The best choice is ab7913, THP1 (Human acute m...
