Description
Additional Information

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). Applications: Suitable for use in Flow Cytometry, ELISA, Western Blot, Immunoprecipitation, Immunohistochemistry and Immunocytochemistry. Other applications not tested. Recommended Dilution: Flow Cytometry: 1:30 Western Blot: 1:5000-1:10,000 Immunoprecipitation: 1:30 Immunohistochemistry: 1:100-1:250 Immunocytochemistry: 1:100-1:250 Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4 degrees C for short-term only. For long-term storage, store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. Manufactured incorporating RabMAb(R) technology under Epitomics US patents, No 5,675,063 and 7,429,487, owned by Abcam.
