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)

Cytokeratins are a subfamily of intermediate filament proteins and are characterized by a remarkable biochemical diversity, represented in epithelial tissues by at least 20 different polypeptides. They range in molecular weight between 40kD and 68kD and isoelectric pH between 4.9-7.8. The individual cytokeratin polypeptides are designated 1 to 20. Cytokeratin 1 has the highest molecular weight and the highest isoelectric pH, while cytokeratin 19 has the lowest molecular weight and a low isoelectric pH. The cytokeratins are divided into the type I and type II subgroups, the type II family members comprising the basic to neutral cytokeratins 1-8, while the type I group comprises the acidic cytokeratins 9-20. The cytokeratins are expressed in combinations which characterize the type of epithelium.\n\nApplications:\nSuitable for use in Immunohistochemistry, Flow Cytometry, Immunocytochemistry, and Western Blot. Other applications not tested.\nOptimum dilutions to be determined by researcher.\n\nRecommended Dilution:\nImmunohistochemistry (frozen sections): 1:50-1:100 with avidin-biotinylated HRP complex (ABC) as detection reagent.\nWestern Blot: 1:50-1:500\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, 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.
