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
modificationsArg-20 is dimethylated, probably to asymmetric dimethylarginine. -

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Cytokeratin 7 antibody [EPR17079] (ab199718)
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.
Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.

Immunoprecipitation - Anti-Cytokeratin 7 antibody [EPR17079] (ab199718)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.
