The term "cytokeratin" began to be used in the late 1970s (for example, see "Intermediate-sized filaments of human endothelial cells" by Franke, Schmid, Osborn and Weber) when the protein subunits of keratin intermediate filaments inside cells were first being identified and characterized. In 2006 a new systematic nomenclature for keratins was created and now the proteins previously called "cytokeratins" are simply called keratins. Over 25, 000 published articles exist in the biomedical research literature that used the term "cytokeratin".;Description:Mouse Anti-Human Cytokeratin Monoclonal Antibody;Host Species:Mouse;Species Reactivity:Human;Clone#:AE1/AF4;Isotype:IgG1, kappa;Application:IHC;Storage:Store antibody products at 2-8°C.
