WebFeb 13, 2009 · High-Molecular-Weight Keratin Antibody Clone 34βE12 (Enzo Diagnostic, Inc, Farmindale, NY, USA) This antibody recognizes K1, K5, K10, and K14, which are expressed in complex epithelia, basal cells (e.g., in prostate), and myoepithelial cells (e.g., in breast). CAM 5.2 (BD Biosciences, San Jose, CA, USA) This antibody reacts with K8 and K18. Cytokeratins are keratin proteins found in the intracytoplasmic cytoskeleton of epithelial tissue. They are an important component of intermediate filaments, which help cells resist mechanical stress. Expression of these cytokeratins within epithelial cells is largely specific to particular organs or tissues. Thus they are used clinically to identify the cell of origin of various human tumors.
