Clone: AE1/AE3.
Background: Pan-Cytokeratin (AE1/AE3) contains two different clones, which label the majority of normal epithelia and carcinoma. Cytokeratins are a group of water soluble filament proteins, which are components of the cytoskeleton of the epidermis and other epithelial cells. Gelelectrophoretic investigation revealed 20 different Cytokeratins, characterised by different molecular sizes and pI-values. They can be subdivided into basic and acid subfamilies. The nomenclature according to Moll et al. (1982) is most commonly used. Basic cytokeratins (52-67 kD) and acid cytokeratins (40, 48, 50, 50', 56,5 kD) CK 1-8, 10, 14-16 and 19 according to the nomenclature by Moll (1982) .
Positive Control: Appendix.
Immunogen: Human epithelial keratins.

Caution: *These antibodies are intended for in vitro research use only. They must not be used for clinical diagnostics and not for in vivo experiments in humans or animals. ** The preservative sodium azide is known to be poisonous and potentially hazardous to health. It should be handled only by trained staff. Despite of the product's low azide concentration it must be handled with care. Dispose according to regional rules!
