Cytokeratins, a group comprising at least 29 different proteins, are characteristic of epithelial and trichocytic cells. Cytokeratin 5, 6 and 8 are members of the type II neutral-to-basic subfamily. Monoclonal antibodies to cytokeratins are specific markers of epithelial cell differentiation and have been widely used as tools in tumor identification and classification. PCK-26 facilitates the typing of normal, metaplastic and neoplastic cells and it may aid in the discrimination of carcinomas and non-epithelial tumors such as sarcomas, lymphomas and neural tumors. It is also useful in detecting micro-metastases in lymph nodes and other tissues and for determining the origin of poorly differentiated tumors.
