Mouse anti-Cytokeratin 7, clone OV-TL 12/30 - 7 ml

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 typically stain positive, and colon and prostate carcinomas that typically lack CK7 expression.CK 7 is a common marker of primary lung adenocarcinomas (almost all cases) with a lower specificity since it is also observed in other primary lung carcinomas and non-pulmonary carcinomas.1 Anti-cytokeratin 7 has also been useful in the differential diagnosis of ovarian neoplasms.This antibody does not recognize intermediate filament proteins.
