Detection of Human 5'-Nucleotidase/CD73 by Western Blot. Western blot shows lysates of U266 human myeloma cell line. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human|
5'‑Nucleotidase/CD73 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5795) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for 5'-Nucleotidase/CD73 at approximately 70 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.
Detection of Human|
5'‑Nucleotidase/CD73 by Simple WesternTM. Simple Western lane view shows lysates of U266 human myeloma cell line, loaded at 0.5 mg/mL. A specific band was detected for 5'‑Nucleotidase/CD73 at approximately 86 kDa (as indicated) using 10 µg/mL of Sheep Anti-Human
5'‑Nucleotidase/CD73 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5795) 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.
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.
