| Product description |
Mouse monoclonal [KS - 1A3] to Cytokeratin 13Epithelial cells and their derivatives characteristically contain intermediate filaments composed of about 20 related polypeptides with molecular weights between 40,000 and 69,000. Each epithelial tissue has a specific and stable pattern of expression of some of these cytokeratin subunits. Epithelium derived tumors maintain the expression of the cytokeratins found in the normal tissue of origin, therefore, carcinomas can be identified and classified by immunocytochemical staining with antibodies that react specifically with cytokeratins. |
