Data Examples
Detection of CD39/ENTPD1 in Mouse Splenocytes by Flow Cytometry. Mouse splenocytes were stained with Mouse CD39/ENTPD1 Antigen Affinity‑purified Polyclonal Antibody (Catalog # AF4398, filled histogram) or control antibody (Catalog # 5-001-A, open histogram), followed by NorthernLights™ 637-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # NL011).
CD39/ENTPD1 in Mouse Liver. CD39/ENTPD1 was detected in perfusion fixed frozen sections of mouse liver using Mouse CD39/ENTPD1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4398) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue).

Background: CD39/ENTPD1

Ectonucleoside triphosphate diphosphohydrolase-1 (NTPDase-1) is an integral membrane protein with an extracellular active site. Recombinant mouse NTPDase-1 was expressed as a protein lacking its N- and C-terminal transmembrane domains, resulting in the secretion of the soluble ectodomain. NTPDase-1 was originally described as CD39, a B lymphocyte cell surface marker (1), but it is also present on the surface of natural killer cells, T cells, and some endothelial cells (2). NTPDase-1 hydrolyzes the beta - and gamma  phosphate residues of nucleotides, preferring ATP as the substrate. Through its hydrolysis of extracellular nucleotides, NTPDase-1 plays a role in the regulation of purinergic signaling (3). NTPDase-1 is involved in the processes of thromboregulation and vascular inflammation (4). The administration of soluble NTPDase-1 may have therapeutic applications for the treatment of some vascular and transplantation-associated diseases (5).
