{"product_id":"biolegend-328204","title":"Biolegend, 328204, Biotin anti-human CD39 Antibody, 100μg","description":"\u003cp\u003eHuman CD39 is an integral membrane protein with two transmembrane domains. It exists as a homotetramer. Expression of CD39 is found on activated lymphocytes, a subset of T cells and B cells, and dendritic cells with weak staining on monocytes and granulocytes. CD39 and CD73 have been found on regulatory T cells, specifically the effector\/memory like T cells. 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 has intrinsic ecto-ATPase activity. Expression of CD39 is induced on T cells and increased on B cells as a late activation antigen.\u003cbr\u003e\n100μg\u003cbr\u003e\nVerified Reactivity: Human, Cynomolgus, Rhesus\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Mouse\u003cbr\u003e\nImmunogen: PHA activated human lymphocytes\u003cbr\u003e\nFormulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.\u003cbr\u003e\nPreparation: The antibody was purified by affinity chromatography, and conjugated with biotin under optimal conditions.\u003cbr\u003e\nConcentration: 0.5 mg\/ml\u003cbr\u003e\nStorage \u0026amp; Handling: The antibody solution should be stored undiluted between 2°C and 8°C. Do not freeze.\u003cbr\u003e\nApplication: FC - Quality tested\u003cbr\u003e\nRecommended Usage: Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤ 2.0 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.\u003cbr\u003e\nApplication Notes: The A1 antibody binds to the human CD39 cell surface antigen and has been shown to block MHC independent target cell recognition by hapten-specific CTL. Additional reported applications (for the relevant formats) include: in vitro CD39 blockade3, immunofluorescence4, immunohistochemistry6, and spatial biology (IBEX)7,8. The Ultra-LEAF™ purified antibody (Endotoxin \u0026lt; 0.01 EU\/µg, Azide-Free, 0.2 µm filtered) is recommended for blocking assays (contact our custom solutions team).\u003cbr\u003e\nApplication References(PubMed link indicates BioLegend citation): Aversa GG, et al. 1988.
