| Application: | Anti-ENTPD1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige . |

| Biochem/physiol Actions: | The gene ENTPD1 (ectonucleoside triphosphate diphosphohydrolase 1) encodes a plasma membrane-bound vascular ATP diphosphohydrolase (ATPDase) that catalyzes the hydrolysis of extracellular ATP and ADP to adenosine, which associates with adenosine receptors and negatively regulates T-cell and natural killer (NK)–cell responses, resulting in a suppressed immune system. The regulatory T cell (Treg) immunosuppressive function is mainly due to the CD39/CD73 pathway that produces adenosine. The expression of CD39 is found to be higher in cancer cells than in normal cells. It is expressed by infiltrating lymphocytes, the tumor stroma, and tumor cells in cancer tissues. It may serve as a therapeutic target for inhibiting tumor cell–mediated immunosuppression. |

| Features and Benefits: | Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section. Every Prestige Antibody is tested in the following ways: • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues. • Protein array of 364 human recombinant protein fragments. |
