Target Information
Cytokeratin 19 is part of 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 pH between 4.9–7.8.
Different human epithelia express distinct cytokeratins, which are related to tissue type and degree of differentiation.
Cytokeratin subtype expression patterns assist in distinguishing epithelial malignancies and are useful in immunohistochemistry, cytopathology, and flow cytometry.
Cytokeratin 19 is not expressed in hepatocytes, making it useful for identifying liver metastasis.
⚠ WARNING: This product can expose you to chemicals including mercury, which is known to the State of California to cause birth defects or other reproductive harm.
