Cytokeratin 8 (Cytokeratin-8, CK 8, CK8, CK-8, Cyk8, Cardiac Autoantigen 2 120kD, Card2, Keratin 8, Keratin-8, K8, KRT8, Keratin Type II, Cytoskeletal 8, K2C8, KO)

Keratins, the intermediate filament proteins of epithelial cells, connect to desmosomes, the cell-cell adhesion structures at the surface membrane. Among the various intermediate filament (IF) proteins, cytokeratin 8 (CK8) is especially remarkable as it is produced early in embryogenesis, is the only type-II CK occurring in many simple epithelial cells, and can also be synthesized in certain non-epithelial cells (1). Keratin 8 and 18 (CK8/18) are the major keratin pair in simple-type epithelia, as found in the liver, pancreas, and intestine (2). While K8/K18 are essential for maintaining structural integrity, there is accumulating evidence indicating that they also exert non-mechanical functions. It has been reported that K8/K18-free hepatocytes from K8-null mice are more sensitive to Fas-mediated apoptosis, in line with an increased Fas density at the cell surface and an altered c-Flip regulation of the anti-apoptotic ERK1/2 signaling pathway (3).\n\nApplications:\nSuitable for use in Western Blot, Immunoprecipitation, Immunohistochemistry and Immunocytochemistry. Other applications not tested.\n\nRecommended Dilution:\nWestern Blot: 1:500 \nImmunoprecipitation: 1:60 \nImmunohistochemistry: 1:100-1:250 \nImmunocytochemistry: 1:100-1:250 \nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. For long-term storage, aliquot and 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.
