Four monoclonal antibodies designated as AMK-6, AMK-10, AMK-16 and AMK-27, were raised against merokeratin prepared from sheep's wool, and their cross-reactivity to epithelial cytokeratins were examined using immunoblot analysis and immunohistochemistry. AMK-16 which was specific to merokeratin in immunoblot analysis, demonstrated specific immunohistochemical staining of wool fibers of the sheep's skin. The other 3 monoclonal antibodies (AMK-6, -10, and -27) showed cross-reactivity towards epithelial cytokeratins with several molecular weights when examined by immunoblot analysis. However, each immunohistochemical staining of the sheep's skin with these monoclonal antibodies appeared to be cell type-specific. These results indicate that merokeratin and certain epithelial cytokeratins share many antigenic epitopes in common, and these monoclonal antibodies against merokeratin from sheep wool will be useful for the analysis of wool-forming cell differentiation.

UI MeSH Term Description Entries
D007120 Immunochemistry Field of chemistry that pertains to immunological phenomena and the study of chemical reactions related to antigen stimulation of tissues. It includes physicochemical interactions between antigens and antibodies.
D007633 Keratins A class of fibrous proteins or scleroproteins that represents the principal constituent of EPIDERMIS; HAIR; NAILS; horny tissues, and the organic matrix of tooth ENAMEL. Two major conformational groups have been characterized, alpha-keratin, whose peptide backbone forms a coiled-coil alpha helical structure consisting of TYPE I KERATIN and a TYPE II KERATIN, and beta-keratin, whose backbone forms a zigzag or pleated sheet structure. alpha-Keratins have been classified into at least 20 subtypes. In addition multiple isoforms of subtypes have been found which may be due to GENE DUPLICATION.
