Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 50 kDa (predicted molecular weight: 50 kDa).
IHC-P 1/50 - 1/100. Perform heat mediated antigen retrieval before commencing with IHC staining protocol. Heat up to 98 degrees C, below boiling, and then let cool for 10-20 min.
  • Application notesIs unsuitable for Flow Cyt,ICC or IP.
  • Target

    • FunctionSpecifically phosphorylates 'Tyr-504' on LCK, which acts as a negative regulatory site. Can also act on the LYN and FYN kinases.
    • Tissue specificityExpressed in lung and macrophages.
    • Sequence similaritiesBelongs to the protein kinase superfamily. Tyr protein kinase family. CSK subfamily.
      Contains 1 protein kinase domain.
      Contains 1 SH2 domain.
      Contains 1 SH3 domain.
    • Post-translational
      Autophosphorylation of Tyr-304 occurs only at abnormally high CSK concentrations in vitro.
    • Cellular localizationCytoplasm. Cell membrane. Mainly cytoplasmic, also present in lipid rafts.

      Lane 1: Wild-type HAP1 cell lysate (20 µg)
      Lane 2: CSK knockout HAP1 cell lysate (20 µg)
      Lane 3: Ramos cell lysate (20 µg)

      Lanes 1 - 4: Merged signal (red and green). Green - ab125005 observed at 50 kDa. Red - loading control, ab8245, observed at 37 kDa.
      ab125005 was shown to specifically react with CSK when CSK knockout samples were used. Wild-type and CSK knockout samples were subjected to SDS-PAGE. ab125005 and ab8245 (loading control to GAPDH) were diluted 1/1000 and 1/10000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 h at room temperature before imaging.
