Description: Cytokeratins are intermediate filament proteins that are widely expressed in many tissues. These proteins are vital components of the cytoskeleton and interact with a number of other proteins. Cytokeratins are usually found in the cytoplasm,although some cytokeratins can be found in the nucleus and the nucleolus. The C-11 monoclonal antibody reacts with conserved epitope in all species tested of cytokeratin 4, 5, 6, 8, 10, 13, and 18. This antibody has been shown to be useful for Western blotting and has also been reported to be useful for immunoprecipitation, immunohistochemistry (paraffin sections), and immunocytochemistry. Hela cell extract was resolved by electrophoresis, transferred to nitrocellulose and probed with monoclonal ant-cytokeratin antibody (clone C-11). Proteins were visualized using a goat anti-mouse secondary conjugated to HRP and a chemiluminescence detection system. Distribution: Cytokeratins are widely expressed proteins usually found in the cytoplasm although some cytokeratins can also be found in the nucleus and the nucleolus Function: Intermediate filament protein involved with the cytoskeleton. Synonyms: Cytokeratin, Keratin Structure: Itermediate filament protein, contains three coiled-coil domains. Cytokeratins exist as heterotetramers composed of two type I and two type II keratin subunits

Specificity: Most cytokeratins interact with a number of other proteins such as 14-3-3, EGF receptor, and many others. reacts with conserved epitope in all species tested. recognizes cytokeratin 4
