Product Specific Information
This antibody recognizes the rod domain of cytokeratin 19 (40 kDa), an intracellular antigen constituting intermediate cytoskeleton filaments. Cytokeratin 19 is not expressed in hepatocytes and is often co-expressed with cytokeratin 7.
Target Information
Cytokeratin 19 belongs to a subfamily of intermediate filament proteins characterized by biochemical diversity, represented in human epithelial tissues by at least 20 different polypeptides. Cytokeratins range in molecular weight from 40–68 kDa and isoelectric point from 4.9–7.8.
Cytokeratin subtype expression patterns are used to distinguish different epithelial malignancies. Cytokeratin antibodies aid in tumor differential diagnosis using immunohistochemistry, cytopathology, and flow cytometry.
Notably, cytokeratin 19 is not expressed in hepatocytes, making it useful for identifying liver metastasis.
