Anti-Cytokeratin, HMW (High Molecular Weight Keratin)

This monoclonal antibody recognizes basic (Type II or HMW) cytokeratins, which include 67kD (CK1), 64kD (CK3), 59kD (CK4), 58kD (CK5), 56kD (CK6), 52kD (CK8). Twenty human keratins are resolved with two-dimensional gel electrophoresis into acidic (pI <5.7) and basic (pI >6.0) subfamilies. The acidic keratins have molecular weights (MW) of 56.5, 55, 51, 50, 50', 48, 46, 45, and 40kD. Monoclonal antibody AE3 recognizes the 65-67, 64, 59, 58, 56, and 52kD keratins of basic subfamily. Many studies have shown the usefulness of keratins as markers in cancer research and tumor diagnosis. AE1/AE3 is a broad spectrum anti pan-keratin antibody cocktail, which differentiates epithelial tumors from non-epithelial tumors e.g. squamous vs. adenocarcinoma of the lung, liver carcinoma, breast cancer, and esophageal cancer.
