  • Title: A panel of monoclonal antibodies to keratin no. 7: characterization and value in tumor diagnosis.

    Journal: Neoplasma; 1990; 37(3):333-42. PubMed ID: 1695327.
    Abstract:
    Reactivity patterns of seven mouse monoclonal antibodies to human keratin 7 were compared using immunoblotting and immunohistochemistry on cultured cells and normal human and animal tissues. Differences in keratin specificities as determined by two-dimensional immunoblots and interspecies cross-reactivity data on 8 mammalian species suggest that at least six nonidentical epitopes of the keratin 7 molecule are recognized by this panel of reagents. Immunohistochemical examination of a panel of various human neoplasms with monoclonal antibodies monospecific for keratins 7, 18 and 19 revealed potential value of keratin subtyping in differential diagnosis of tumors in general and in subclassification of carcinomas in particular.
