Our Abpromise guarantee covers the use of ab86175 in the following tested applications.

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

Application Abreviews Notes
IHC-P Use a concentration of 5 µg/ml.
WB Use a concentration of 1 µg/ml. Predicted molecular weight: 63 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.


  • Function
    Participates in the Wnt signaling pathway. Binds to DNA and acts as a repressor in the absence of CTNNB1, and as an activator in its presence. Necessary for the terminal differentiation of epidermal cells, the formation of keratohyalin granules and the development of the barrier function of the epidermis (By similarity). Down-regulates NQO1, leading to increased mitomycin c resistance.
  • Tissue specificity
    Detected in hair follicles and skin keratinocytes, and at lower levels in stomach epithelium.
  • Sequence similarities
    Belongs to the TCF/LEF family.
    Contains 1 HMG box DNA-binding domain.
  • Domain
    The putative Groucho interaction domain between the N-terminal CTNNB1 binding domain and the HMG-box is necessary for repression of the transactivation mediated by TCF7L1 and CTNNB1.

  • Anti-TCF7L1 antibody (ab86175) at 1 µg/ml (5% skim milk/ PBS buffer) + 293T cell lysate at 10 µg with gel concentration: 12%

    HRP conjugated anti-Rabbit IgG at 1/50000 dilution

    Predicted band size: 63 kDa
    Observed band size: 65 kDa (why is the actual band size different from the predicted?)
    Additional bands at: >90 kDa, 38 kDa, 46 kDa. We are unsure as to the identity of these extra bands.

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human skin tissue labelling TCF7L1 with ab86175 at 5.0µg/ml.
