Description
The A1 monoclonal antibody specifically recognizes human CD39 which is also known as Ecto-ATP diphosphohydrolase 1 (Ecto-ATPase 1 or Ecto-ATPDase 1), Ecto-apyrase or NTPDase 1. CD39 is a ~78 kDa integral membrane glycoprotein that is encoded by ENTPD1 (Ectonucleoside triphosphate diphosphohydrolase 1). CD39 contains two transmembrane domains, one having a N- and the other a C-terminal cytoplasmic tail, and a large extracellular domain that has the enzymatic site. CD39 is also known as Lymphoid cell activation antigen because its expression is induced upon activation of T and B cells. CD39 is variably expressed on some regulatory T cells, NK cells, granulocytes, monocytes, dendritic cells, Langerhans cells, endothelial cells, platelets, and neurons. CD39 is a member of the ectonucleoside triphosphate dihydrolases (E-NTPDases) family that is involved in the regulation of extracellular nucleotide catabolism by controlling the extracellular nucleoside triphosphate pool (NTP). It functions as an ectoenzyme that can hydrolyze both nucleoside triphosphates and diphosphates such as ATP and ADP and thereby suppress inflammation and regulate platelet activation as well as purinergic neurotransmission. The ectoenzymes CD39 and CD73 can act in tandem to enable regulatory T cells (Treg) to generate immunosuppressive adenosine and thereby regulate immune responses.
BD® CompBeads can be used as surrogates to assess fluorescence spillover (Compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application.
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions and unreacted dye was removed.
1. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
2. An isotype control should be used at the same concentration as the antibody of interest.
3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
