Keratins are cytoplasmic intermediate filament proteins expressed by epithelial cells. Cytokeratin 20 is a type I keratin that is a part of mature enterocytes and goblet cells and is specifically found in the gastric and intestinal mucosa. This antibody is useful in the differentiation of specific types of simple epithelial cells of the urinary tract as well as normal and malignantly transformed epithelia. It detects adenocarcinomas of the colon, stomach, pancreas and biliary system, mucinous ovarian tumors, transitional-cell and Merkel cell carcinomas.
