Notes:
The present paper describes the production and characterization of two monoclonal antibodies, K20 and K92. Immunohistological staining showed these two antibodies to be specific for keratinizing epithelium. However, whereas K20 stained all layers of the epidermis K92 reacted with only the suprabasal epidermal layers. Immunoblotting studies with preparations of keratins from both the non-cornified (i.e. the basal, spinous and granular layers) and cornified (stratum corneum) layers of epidermis showed that K20 recognized the 46, 48, 50, 55, 56, 56.5, 59, 61, 62, 64, 65, 66 and 67 kd bands, of which the 50 and 46 kd bands appeared to be masked in tissue sections. In contrast, antibody K92 was more restricted in its activity, recognizing only the 55 and 56 kd bands strongly. These antibodies were used in the study of various epithelial disorders and revealed alterations in the epithelial intermediate filament expression in both benign and malignant disease processes.
