KRT19 Protein


Home / Products / KRT19


Official Full Name keratin 19
Background Cytokeratin 19 is a type I acidic subfamily of intermediate filament protein that is expressed in stratified and simple type epithelia. Keratin 19 is not expressed in hepatocytes; therefore, antibody to keratin 19 is useful in the identification of liver metastasis. The degree of keratin 19 positivity in breast cancer distinguishes malignant from benign tumors. Keratin 19 is often co-expressed with keratin 7.
