A STUDY OF HUMAN EPIDERMAL PROTEINS

[摘要] For a study of epidermal proteins, the epidermis of human abdominal autopsy skin was separated from the dermis, homogenized, and extracted with various solvents. The components of the extracts, in turn, were identified by paper electrophore-sis (7). These investigations led to a simple fractionation method for identification of epidermal proteins which is schematically shown. By this fractionation method, in addition to epidermal keratin, 2 different soluble proteins were identified. These are considered to be the main soluble protein constituents of human abdominal epidermis.
