Anti-Cytokeratin, pan (Epithelial Marker) Polyclonal Antibody

Twenty human keratins are resolved with two-dimensional gel electrophoresis into acidic (pI 6.0) subfamilies. This antibody cocktail recognizes acidic (Type I or LMW) and basic (Type II or HMW) cytokeratins, which 67kDa (CK1) ; 64kDa (CK3) ; 59kDa (CK4) ; 58kDa (CK5) ; 56kDa (CK6) ; 52kDa (CK8) ; 56.5kDa (CK10) ; 50kDa (CK14) ; 50kDa (CK15) ; 48kDa (CK16) ; 40kDa (CK19) . Many studies have shown the usefulness of keratins as markers in cancer research and tumor diagnosis. It is a broad spectrum anti pan-cytokeratin antibody, which differentiates epithelial tumors from non-epithelial tumors e.g. squamous vs. adenocarcinoma of the lung, liver carcinoma, breast cancer, and esophageal cancer. It may be useful to characterize the source of various neoplasms and to study the distribution of cytokeratin containing cells in epithelia during normal development and during the development of epithelial neoplasms. This antibody stains cytokeratins present in normal and abnormal human tissues and has high sensitivity in the recognition of epithelial cells and carcinomas.
