  • Application notes
    Is unsuitable for Flow Cyt or IP.
  • Target

    • Function

      Hydrolyzes extracellular nucleotides into membrane permeable nucleosides.
    • Involvement in disease

      Defects in NT5E are the cause of calcification of joints and arteries (CAJA) [MIM:211800]. A condition characterized by adult-onset calcification of the lower extremity arteries, including the iliac, femoral and tibial arteries, and hand and foot capsule joints. Age of onset has been reported as early as the second decade of life, usually involving intense joint pain or calcification in the hands.
    • Sequence similarities

      Belongs to the 5'-nucleotidase family.
    • Cellular localization

      Cell membrane.

    • All lanes : Anti-CD73 antibody [EPR6114] (ab133582) at 1/1000 dilution

      Lane 1 : Wild-type HEK-293 whole cell lysate
      Lane 2 : NT5E knockout HEK-293 whole cell lysate
      Lane 3 : A375 whole cell lysate

      Lysates/proteins at 20 µg per lane.

      Predicted band size: 63 kDa

      Lanes 1 - 3: Merged signal (red and green). Green - ab133582 observed at 63 kDa. Red - loading control, ab8245, observed at 37 kDa.

      ab133582 was shown to recognize NT5E in wild-type HEK-293 cells as signal was lost at the expected MW in NT5E knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and NT5E knockout samples were subjected to SDS-PAGE. The membrane was blocked with 3% Milk. Ab133582 and ab8245 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

    • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of Human lung carcinoma tissue sections labeling CD73 with Purified ab133582 at 1:2000 dilution (1.12 µg/ml). Heat mediated antigen retrieval was performed using ab93684 (Tris/EDTA buffer, pH 9.0). ImmunoHistoProbe one step HRP Polymer (ready to use)was used. Negative control:PBS instead of the primary antibody. Hematoxylin was used as a counterstain.
    • Immunocytochemistry/ Immunofluorescence analysis of A375 (Human malignant melanoma epithelial cell) cells labeling CD73 with Purified ab133582 at 1:250 dilution (8.9 µg/ml). Cells were fixed in 4% Paraformaldehyde and permeabilized with 0.1% tritonX-100. Cells were counterstained with Ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) 1:200 (2.5 µg/ml). Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) was used as the secondary antibody at 1:1000 (2 µg/ml) dilution. DAPI nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control.
