Part Description

LP35595-5   Cytokeratin 20
Keratin 20, often abbreviated CK20, is a protein that in humans is encoded by the KRT20 gene.

Keratin 20 is a type I cytokeratin. It is a major cellular protein of mature enterocytes and goblet cells and is specifically found in the gastric and intestinal mucosa.

In immunohistochemistry, antibodies to CK20 can be used to identify a range of adenocarcinomata arising from epithelia that normally contain the CK20 protein. For example, the protein is commonly found in colorectal cancer, transitional cell carcinomas and in Merkel cell tumours, but is absent in lung cancer, prostate cancer, and non-mucinous ovarian cancer. It is often used in combination with antibodies to CK7 to distinguish different types of glandular tumour. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.
