Application Abreviews Notes
WB 1/1000. Detects a band of approximately 15-20 kDa (predicted molecular weight: 12 kDa).
IHC-P Use at an assay dependent concentration.
Flow Cyt 1/20.

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

IP 1/50.
  • Application notesIs unsuitable for ICC.
  • Target

    • FunctionRegulates eIF4E activity by preventing its assembly into the eIF4F complex. Mediates the regulation of protein translation by hormones, growth factors and other stimuli that signal through the MAP kinase and mTORC1 pathways.
    • Sequence similaritiesBelongs to the eIF4E-binding protein family.
    • Post-translational
      Phosphorylated on serine and threonine residues in response to insulin, EGF and PDGF. Phosphorylation at Thr-37, Thr-46, Ser-65 and Thr-70 is regulated by mTORC1. Phosphorylated upon DNA damage, probably by ATM or ATR.

    • Predicted band size : 12 kDa

      Lane 1: Wild-type HAP1 cell lysate (20 µg)
      Lane 2: eIF4EBP1 knockout HAP1 cell lysate (20 µg)
      Lane 3: Hek293 cell lysate (20 µg)
      Lane 4: K562 cell lysate (20 µg)
      Lanes 1 - 4: Merged signal (red and green). Green - ab32130 observed at 20 kDa. Red - loading control, ab8245, observed at 37 kDa.
      ab32130 was shown to specifically react with eIF4EBP1 when eIF4EBP1 knockout samples were used. Wild-type and eIF4EBP1 knockout samples were subjected to SDS-PAGE. ab32130 and ab8245 (loading control to GAPDH) were diluted 1/1000 and 1/2000 respectively and incubated overnight at 4°C. Blots were developed with goat anti-rabbit IgG (H + L) and goat anti-mouse IgG (H + L) secondary antibodies at 1/10 000 dilution for 1 h at room temperature before imaging.
