The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IP Use at 2-5 µg/mg of lysate.
IHC-P 1/500 - 1/2000. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
WB 1/2000 - 1/10000. Detects a band of approximately 85 kDa (predicted molecular weight: 73 kDa).


  • Function

    Binds specifically to oligomers of E-box motifs. May play important roles during development of the nervous system as well as in other organ systems.
  • Tissue specificity

    Expressed in several tissues and cell types including skeletal muscle, thymus, and a B-cell line.
  • Sequence similarities

    Contains 1 basic helix-loop-helix (bHLH) domain.
  • Domain

    the 9aaTAD motif is a transactivation domain present in a large number of yeast and animal transcription factors.
  • Post-translational

    Phosphorylated upon DNA damage, probably by ATM or ATR.
  • Cellular localization

  • All lanes : Anti-TCF12 antibody (ab70746) at 1/10000 dilution

    Lane 1 : HeLa whole cell lysate at 50 µg
    Lane 2 : HeLa whole cell lysate at 15 µg
    Lane 3 : HeLa whole cell lysate at 5 µg

    Developed using the ECL technique.

    Predicted band size: 73 kDa
    Observed band size: 85 kDa
    why is the actual band size different from the predicted?
    Additional bands at: 100 kDa, 120 kDa, 190 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 30 seconds
  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human breast carcinoma tissue labelling TCF12 with ab70746 at 1/1000 (1µg/ml). Detection: DAB.
  • 1mg whole cell lysate from HeLa cells was immunprecipitated with ab70746 at 3µg/mg lysate. For the subsequent western blot, 20% of the immunoprecipitate was loaded per lane, and probed with ab707345 at 1ug/ml. Detection: chemiluminescence with exposure time of 10 seconds
