General description

Cytokeratin 14 (CK 14) is a 50 kD polypeptide found in basal cells of squamous epithelia, some glandular epithelia, myoepithelium, and mesothelial cells. Anti-CK 14 has been demonstrated to be useful in differentiating squamous cell carcinomas from other epithelial tumors. This antibody has also been useful in separating oncocytic tumors of the kidney from it′s renal cell mimic, as well as in determining metaplastic carcinomas of the breast.
