Clone 1F22 is a ZooMAb rabbit recombinant monoclonal antibody that specifically detects 5′-Nucleotidase (CD73). It targets an epitope within the N-terminal half.

His-tagged recombinant fragment corresponding to 244 amino acids from the N-terminal half of mature human CD73.

Anti-CD73 (NT5E), clone 1F22 ZooMAb, Cat. No. ZRB1035, is a recombinant Rabbit monoclonal antibody that detects CD73 (NT5E) and is tested for use in Affinity Binding Assay, Flow Cytometry, Immunohistochemistry (Paraffin), and Western Blotting.

Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected CD73 (NT5E) in A375 cells and in rat spleen and mouse spleen tissue lysates.

Affinity Binding Assay: A representative lot of this antibody bound recombinant NT5E/CD73 protein with a KD of 4.2 x 10-8 in an affinity binding assay.

Immunohistochemistry (Paraffin) Analysis: A 1:1,000 dilution from a representative lot detected CD73 (NT5E) in human tonsil tissue sections.

Flow Cytometry Analysis: 0.1 μg from a representative lot detected CD73 (NT5E) in one million HT29 cells.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user

5′-Nucleotidase (UniProt: P21589; also known as EC:3.1.3.5, 5′-NT, Ecto-5′-nucleotidase, CD73) is encoded by the NT5E (also known as NT5, NTE) gene (Gene ID: 4907) in human. CD73 is a GPI-anchor membrane glycoprotein that is expressed in most tissues and is involved in the control of a variety of physiological responses including epithelial ion and fluid transport, ischemic preconditioning, tissue injury, platelet function, hypoxia and vascular leak. It is also widely expressed on several tumor tissues and its higher expression levels are associated with tumor neovascularization, invasiveness, and metastasis. Its biological actions are mainly due to its regulated enzymatic phosphohydrolytic activity on extracellular nucleotides. It hydrolyzes extracellular nucleotides into membrane permeable nucleosides and displays AMP-, NAD-, and NMN-nucleosidase activities. CD73 is synthesized with a signal peptide (aa 1-26) and a C-terminal propeptide (aa 550-574) that are subsequently cleaved off to generate the mature form (aa 27-549). Its substrate binding site is localized to amino acids 500-506. Mutations in NT5E gene have been linked to adult-onset of calcification of joints and arteries. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
