General description

Anti-cytokeratin, high molecular weight (AE3) is capable of recognizing all basic keratins; therefore, it is a broadly reactive antibody staining most epithelia and their neoplasms. Members of the acidic and basic subfamilies are found together in pairs. Since each epithelium contains at least one acidic and one basic keratin, this antibody is used to observe the distribution of keratin-containing cells in normal epithelia and to identify neoplasms derived from such epithelium.

Historically, antibodies to cytokeratin intermediate filaments have been models of target specificity. In most diagnostic settings, the utility of these antibodies was unquestioned; reactivity for cytokeratin was dogmatically equated with epithelial differentiation. Recently, however, the diagnostic importance of these antibodies
