U-VUE Biomarker Datasheet - pan-CK

Alternative Name:pan-Cytokeratin
Isotype:Mouse IgG1
Main cell types:Cells of epithelian origin- including most carcinomas
Subcellular Location:Cytoplasm
Positive control:Tonsil

Cytokeratins play a cytoskeletal role in epithelial tissue and are an important component of intermediate filaments. These provide a structural framework for the cell and help resist mechanical stress. The mixture of AE1 and AE3 clones are able to detect a mixture of low and high molecular weight cytokeratins, thus identifying a broad range of cytokeratins. This marker can be used to identify the epithelial nature of tissue and tumors.

IHC: Anti-pan-CK antibody [AE1/AE3] staining normal tonsil FFPE tissue (brown). Hematoxylin counterstain in blue.

IHC: Anti-pan-CK antibody conjugate [AE1/AE3] staining normal tonsil FFPE tissue (brown). Hematoxylin counterstain in blue.

ISP: Anti-pan-CK antibody conjugate [AE1/AE3] staining normal tonsil FFPE tissue (green). Nuclear counterstain in blue.
