Application Abreviews Notes
WB 1/1000 - 1/5000. Detects a band of approximately 68 kDa (predicted molecular weight: 72 kDa).
IHC-P Use at an assay dependent concentration.
Flow Cyt 1/100.

ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.

  • Application notesIs unsuitable for IP.
  • Target

    • FunctionPlays a role in T-cell proliferation and differentiation.
    • Tissue specificityT-cell lines and natural killer cell lines.
    • Involvement in diseaseDefects in ITK are the cause of lymphoproliferative syndrome EBV-associated autosomal type 1 (LPSA1) [MIM:613011]. LPSA1 is a rare immunodeficiency characterized by extreme susceptibility to infection with Epstein-Barr virus (EBV). Inadequate immune response to EBV can have a fatal outcome. Clinical features include splenomegaly, lymphadenopathy, anemia, thrombocytopenia, pancytopenia, recurrent infections. There is an increased risk for lymphoma.
    • Sequence similaritiesBelongs to the protein kinase superfamily. Tyr protein kinase family. TEC subfamily.
      Contains 1 Btk-type zinc finger.
      Contains 1 PH domain.
      Contains 1 protein kinase domain.
      Contains 1 SH2 domain.
      Contains 1 SH3 domain.
    • Cellular localizationCell membrane. Localizes to cell surface receptors in the plasma membrane after stimulation with respective receptors (TCR, CD28, CD2) in T-cells.

    • Anti-ITK antibody [Y401] (ab32039) at 1/5000 dilution + Jurkat cell lysate

      Predicted band size : 72 kDa
      Observed band size : 68 kDa (why is the actual band size different from the predicted?)
    • Ab32039 at a 1/250 dilution, staining ITK in paraffin embedded human lymph node tissue by Immunohistochemistry.
    • Overlay histogram showing Jurkat cells stained with ab32039 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab32039, 1/100 dilution) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-rabbit IgG (H+L) (ab96899) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was rabbit IgG (1µg/1x106 cells ) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in Jurkat cells fixed with 80% methanol (5 min)/permeabilized in 0.1% PBS-Tween used under the same conditions.
