General description

Anti-cytokeratin 7 reacts with proteins that are found in most ductal, glandular, transitional, and biliary duct epithelial cells. Cytokeratin 7 (CK7) labeling can help distinguish between lung, breast carcinomas, and urothelial carcinomas that are typically stain positive, and colon and prostate carcinomas that typically lack CK7 expression. CK7 is a common marker of primary lung adenocarcinomas and is observed in other primary lung carcinomas and non-pulmonary carcinomas. Anti-cytokeratin 7 has also been useful in the differential diagnosis of ovarianneoplasms.
