Application Abreviews Notes
WB 1/4000. Detects a band of approximately 45, 51 kDa (predicted molecular weight: 51 kDa).

Target

  • Function

    Blocks interferon-dependent interphase and stimulates DNA synthesis in cells. Involved in the translational regulation of the human papillomavirus type 16 E7 mRNA (HPV16 E7).
  • Tissue specificity

    Expressed in cultured epidermal, bronchial and mesothelial cells but absent in colon, ectocervix and liver. Observed throughout the glandular cells in the junction between stomach and esophagus but is absent in the esophagus.
  • Sequence similarities

    Belongs to the intermediate filament family.
  • Post-translational
    modifications

    Arg-20 is dimethylated, probably to asymmetric dimethylarginine.
  • Cellular localization

    Cytoplasm.

  • Immunohistochemical analysis of paraffin-embedded Mouse lung tissue labeling Cytokeratin 7 with ab199718 at 1/1600 dilution followed by Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution. Cytoplasm staining on mouse lung tissue 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.

  • All lanes : Anti-Cytokeratin 7 antibody [EPR17079] (ab199718) at 1/20000 dilution

    Lane 1 : Mouse lung lysate

    Exposure time: 15 seconds


    ~45 kDa bands are supported by the literature and competitor’s products, which may be an isoform. The observed MW is consistent with what has been described in the literature PMID:16265353.

  • Immunohistochemical analysis of paraffin-embedded Mouse colon tissue labeling Cytokeratin 7 with ab199718 at 1/1600 dilution followed by Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/500 dilution. Cytoplasm staining on mouse colon tissue 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.

  • Cytokeratin 7 was immunoprecipitated from 1mg of Mouse skin whole cell extract with ab199718 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab199718 at 1/1000 dilution. Anti-Rabbit IgG (HRP), specific to the non-reduced form of IgG, was used as secondary antibody at 1/1500 dilution.

    Lane 1: Mouse skin whole cell extract 10 µg (Input). Lane 2: ab199718 IP in Mouse skin whole cell extract. Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab199718 in Mouse skin whole cell extract.
    Blocking and dilution buffer and concentration: 5% NFDM/TBST.
