Our Abpromise guarantee covers the use of ab9585 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
WB Use a concentration of 0.1 - 0.2 µg/ml. Can be blocked with Recombinant TGF alpha protein (ab9587).
Neutralising Use at an assay dependent concentration.

To yield one-half maximal inhibition [ND50] of the biological activity of hTGF alpha (0.5 ng/ml), a concentration of 2.5 - 2.7 µg/ml of this antibody is required.

Sandwich ELISA Use at an assay dependent concentration.

To detect Human TGF-α by sandwich ELISA (using 100 μl/well antibody solution) a concentration of 0.5 - 2.0 μg/ml of this antibody is required. The antibody, in conjunction with biotinylated Anti-Human TGF-α ab83159 as a detection antibody, allows the detection of at least 0.2 - 0.4 ng/well of recombinant Human TGF-α.

ELISA Use a concentration of 0.5 µg/ml.
IHC-P Use a concentration of 0.25 µg/ml.


  • Function

    TGF alpha is a mitogenic polypeptide that is able to bind to the EGF receptor and to act synergistically with TGF beta to promote anchorage-independent cell proliferation in soft agar.
  • Tissue specificity

    Isoform 1, isoform 3 and isoform 4 are expressed in keratinocytes and tumor-derived cell lines.
  • Sequence similarities

    Contains 1 EGF-like domain.
  • Cellular localization

    Cell membrane and Secreted > extracellular space.

  • ab9585 at 0.25 µg/ml staining human breast invasive ductal carcinoma tissue by IHC-P.  The antibody was incubated for two hours at room temperature.  An HRP-labeled polymer detection system was used with DAB chromogen. Heat induced antigen retrieval was performed with a pH 6.0 Sodium Citrate buffer.
