CK19
Also known as: Cytokeratin 19
Use
Cytokeratin 19 (CK19) is a member of the type I acidic keratins subfamily and is expressed in various human tissues. It labels ductal and glandular epithelia, prostatic epithelia, and non-keratinizing squamous epithelia. This antibody is useful in diagnosing breast and cervical carcinoma. CK19 is not expressed in hepatocytes, helping to distinguish liver metastasis from hepatocellular carcinomas.

Limitations
As CK19 is not expressed in hepatocytes, it may be useful in distinguishing between liver metastasis and hepatocellular carcinoma, but may not be reliable for other types of carcinoma or tissues where CK19 is expressed.
