Immunogen PHA activated human lymphocytes.
Clone A1
Isotype IgG1
Specificity This antibody binds to the CD39 cell surface antigen, a 70-100 kDa molecule expressed on peripheral blood B cells, monocytes and T cell clones. CD39 has intrinsic ecto-ATPase activity. Expression is induced on T cells and increased on B cells as a late activation antigen. This antibody has been shown to block MHC independent target cell recognition by hapten-specific CTL.
Purification Affinity Chromatography on Protein G.
Alternative Name CD39 / ENTPD1 (ENTPD1 Antibody Abstract)
Background Human CD39 is found on most mature B cells, activated NK cells and activated T cells. CD39 is also weakly expressed on granulocytes. CD39 has homology to the Nmyc family of proteins and was recently cloned. CD39 can hydrolyze both nucleoside triphosphates and diphosphates. CD39 is the dominant ecto nucleotidase of vascular and placental trophoblastic tissues and appears to modulate the functional expression of type 2 purinergic (P2) G protein coupled receptors (GPCRs). CD39 transgenic mice exhibit impaired platelet aggregation, prolonged bleeding times, and resistance to systemic thromboembolism. There is a correlation between ATP hydrolysis and triglycerides in patients with chronic heart disease, suggesting a relationship between ATP diphosphohydrolase and thrombogenesis. Depolarization causes the endothelial production of superoxide, which inhibits the activity of endothelial CD39 and enhances platelet aggregation. After exercise, all subjects showed a significant reduction of CD39 expression in platelet and an increase of CD39 expression in B lymphocytes.Synonyms: ATPDase, Ecto-ATP diphosphohydrolase, Ecto-apyrase, Ectonucleoside triphosphate diphosphohydrolase 1, Lymphoid cell activation antigen, NTPDase 1
