Anti-Basic Cytokeratin Purified

Description: The monoclonal antibody AE3 recognizes many members of the basic (Type II) cytokeratin family. Cytokeratins are intermediate filament proteins comprising one component of the cytoskeleton. There are two large families of cytokeratins, acidic and basic, but all contain the same basic domains (i.e. an α-helical core with an N- and C-terminal domain). The proteins are expressed in epithelial cells, but are developmentally regulated. Many tumors also express these cytokeratins, and their expression can help identify the origin of a neoplasm.

The AE3 monoclonal antibody recognizes the 65 to 67 triplet, 64, 59, 58, 56, and 52kD proteins (also known as cytokeratin 1, 2, 3, 4, 5, 6, 7 and 8) in mouse, human, rat, primate (cynomolgus and rhesus), dog, cat, rabbit and chicken.
