Target

  • 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.

  • Immunohistochemical analysis of paraffin-embedded Human hepatocellular carcinoma tissue labeling TGF alpha with ab208156 at 1/4000 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution. Cytoplasm staining on the cancer cells of Human hepatocellular carcinoma is observed. Counter stained with Hematoxylin.

    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab208156).

  • Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized HepG2 (Human liver hepatocellular carcinoma cell line) cells labeling TGF alpha with ab208156 at 1/100 dilution, followed by Goat Anti-Rabbit IgG (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution (green). Confocal image showing cytoplasmic staining on HepG2 cell line. The nuclear counter stain is DAPI (blue). Tubulin is detected with Anti-alpha Tubulin antibody  -Loading Control (ab7291) at 1/1000 dilution and Goat Anti-Mouse IgG  (AlexaFluor®594) preadsorbed (ab150120) at 1/1000 dilution (red).

    The negative controls are as follows:
    -ve control 1: ab208156 at 1/100 dilution followed by ab150120 at 1/1000 dilution.
    -ve control 2: ab7291  at 1/1000 dilution followed by ab150077  at 1/1000 dilution.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab208156).

  • Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized HepG2 (Human liver hepatocellular carcinoma cell line) cells, treated with Brefeldin A (10 µM, 18 hours), labeling TGF alpha with ab208156 at 1/100 dilution, followed by Goat Anti-Rabbit IgG (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution (green). Confocal image showing cytoplasmic staining on HepG2 cells, treated with Brefeldin A (10 µM, 18 hours). The nuclear counter stain is DAPI (blue). Tubulin is detected with Anti-alpha Tubulin antibody - Loading Control (ab7291) at 1/1000 dilution and Goat Anti-Mouse IgG  (AlexaFluor®594) preadsorbed (ab150120) at 1/1000 dilution (red).

    -ve control 2: ab7291  at 1/1000 dilution followed by ab150077 at 1/1000 dilution.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab208156).

  • TGF alpha was immunoprecipitated from 1mg of HepG2 (Human liver hepatocellular carcinoma cell line) whole cell lysate with ab208156 at 1/40 dilution. Western blot was performed from the immunoprecipitate using ab208156 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10000 dilution.

    Lane 1: HepG2 whole cell lysate 10µg (Input).

    Lane 2: ab208156 IP in HepG2 whole cell lysate.

    Lane 3: Rabbit IgG,monoclonal - Isotype Control (ab172730) instead of ab208156 in HepG2 whole cell lysate.

    Blocking and dilution buffer and concentration: 5% NFDM/TBST.

    Exposure time: 1 second.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab208156).

  • TGF alpha was immunoprecipitated from 1mg of Ramos (Human Burkitt's lymphoma cell line) whole cell lysate with ab208156 at 1/40 dilution. Western blot was performed from the immunoprecipitate using ab208156 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/10000 dilution.

    Lane 1: Ramos whole cell lysate, 10µg (Input).

    Lane 2: ab208156 IP in Ramos whole cell lysate.

    Lane 3: Rabbit IgG,monoclonal [EPR25A]-Isotype Control (ab172730) instead of ab208156 in Ramos whole cell lysate.

    Blocking and dilution buffer and concentration: 5% NFDM/TBST.

    Exposure time: 30 seconds.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab208156).

  • This IHC data was generated using the same anti-TGF alpha antibody clone [EPR15346] in a different buffer formulation (cat# ab208156).

    Immunohistochemical analysis of paraffin-embedded Human liver tissue labeling TGF alpha with ab208156 at 1/4000 dilution, followed by Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution. Cytoplasmic staining on Human liver is observed. Counter stained with Hematoxylin.

    Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution.
