Data Examples
Detection of 5'-Nucleotidase/CD73 in Human Peripheral Blood Lymphocytes by Flow Cytometry. Human peripheral blood lymphocytes were labeled with Mouse Anti-Human/Equine 5'-Nucleotidase/CD73 Mono­clonal Antibody (Catalog # MAB5795) followed by Allophycocyanin-conjugated Anti-Mouse IgG F(ab')2 Secondary Antibody (Catalog # F0101B) and Human CD19 PE-conjugated Monoclonal Antibody (Catalog # FAB4867P). Quadrant markers were set based on control antibody staining (Catalog # MAB0041).
Detection of 5'‑Nucleotidase/CD73 in Equine PBMCs by Flow Cytometry. Equine peripheral blood mononuclear cells (PBMCs) were stained with Mouse Anti-Human/Equine 5'-Nucleotidase/CD73 Monoclonal Antibody (Catalog # MAB5795, filled histogram) or isotype control antibody (Catalog # MAB004, open histogram), followed by Phycoerythrin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0102B).

Background: 5'-Nucleotidase/CD73

5'-Nucleotidase (also [ecto]-5'-nucleotidase/5'-NT, designated CD73) is a variably glycosylated, 69-73 kDa member of the 5'-Nucleotidase family of enzymes. It is expressed on multiple cell types, including vascular endothelium, transitional and nonkeratinized epithelium, cardiomyocytes, small intestine epithelium, FoxP3+ Treg lymphocytes, FDCs and B cells. 5'-Nucleotidase hydrolyzes AMP to adenosine and phosphate. This creates diffusible nucleosides necessary for cell homeostasis, and a ligand for cell membrane adenosine receptors. Mature human 5'-Nucleotidase is a 523 amino acid (aa) GPI-linked protein (aa 27-549). It contains a large Zn‑dependent nucleotidase catalytic region (aa 28-532) and a C-terminal substrate binding site (aa 500-506). On the cell surface it exists as a disulfide-linked homodimer. Two splice variants are reported. One shows a deletion of aa 405-454, and a second possesses a 12 aa substitution for aa 253-574. Over aa 1-511, human 5'‑Nucleotidase shares 88% aa identity with both mouse and rat 5'-Nucleotidase.
