Background	Cytokeratin 20 is a 46 kDa intermediate filament protein whose expression is restricted primarily to gastric and intestinal epithelium, urothelium, and Merkel cells. This antibody is highly specific to cytokeratin 20 and shows no cross-reactivity with other IFPs. Cytokeratin 20 is a unique type I keratin that is expressed in adenocarcinomas of the colon stomach, pancreas and bile system. It is also expressed in mucinous ovarian tumors, transitional cell carcinomas of the urinary tract, and Merkel cell carcinomas. This antibody is essentially non-reactive in squamous cell carcinomas and adenocarcinomas of the breast, lung, and endometrium, non-mucinous tumors of the ovary, and small cell carcinomas. This antibody is often used in conjunction with CK7 and other antibodies to distinguishing colon carcinomas (CK20+), from ovarian, pulmonary, and breast carcinomas.
Synonyms	Cytokeratin 20, Keratin-20, KRT20, CK20, K20, Protein IT
