{"product_id":"biolegend-328221","title":"Biolegend, 328221, Purified anti-human CD39 (Maxpar® Ready) 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 and EDTA.\u003cbr\u003e\nPreparation: The antibody was purified by affinity chromatography.\u003cbr\u003e\nConcentration: 1.0 mg\/ml\u003cbr\u003e\nStorage \u0026amp; Handling: The antibody solution should be stored undiluted between 2°C and 8°C.\u003cbr\u003e\nApplication: FC - Quality tested CyTOF®, IHC-P - Verified\u003cbr\u003e\nRecommended Usage: This product is suitable for use with the Maxpar® Metal Labeling Kits. For metal labeling using Maxpar® Ready antibodies, proceed directly to the step to Partially Reduce the Antibody by adding 100 µl of Maxpar® Ready antibody to 100 µl of 4 mM TCEP-R in a 50 kDa filter and continue with the protocol. Always refer to the latest version of Maxpar® User Guide when conjugating Maxpar® Ready antibodies.\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\nAdditional Product Notes: Maxpar® is a registered trademark of Standard BioTools Inc.\u003cbr\u003e\nApplication References(PubMed link indicates BioLegend citation): Aversa GG, et al. 1988.

While it is likely that this will work in majority of the situations, it is best to use the non-EDTA formulated version of the same clone for flow cytometry testing. The presence of EDTA in some situations might negatively affect staining.\u003cbr\u003e\nQ: I am having difficulty observing a signal after conjugating a metal tag to your Maxpar® antibody.

The regular purified format clones are formulated in solution that does not contain any EDTA. Both formulations are however without any extra carrier proteins.\u003c\/p\u003e","brand":"Biolegend","offers":[{"title":"Default Title","offer_id":46862516879529,"sku":"328221","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/biolegend-328221","provider":"Iright","version":"1.0","type":"link"}
