Monoclonal Rabbit Supernatant E B IP IH IC FC
Keratins are cytoplasmic intermediate filament proteins expressed by epithelial cells. Keratin 7 (CK7) is expressed in a wide range of epithelial structures in humans. The expression pattern in mice is similar to the reported human distribution, with substantial expression observed in lung, bladder, mesothelium, hair follicle, and ductal structures (1). Protein expression levels of CK7 appear significantly higher in chromophobe RCC compared to oncocytoma (p < 0.001). Studies provide further evidence that CK7 and parvalbumin immunostains may be useful in differentiating oncocytoma from chromophobe RCC in problematic cases (2). Also, the pattern of immunohistochemical expression of CK7 along with CK20 is commonly used to assess possible primary sites of metastatic carcinomas (3).
