    Author: King CS, Dykes PJ, Marks R.
    Journal: J Invest Dermatol; 1982 Nov; 79(5):297-302. PubMed ID: 6752291.
    Abstract:
    Nonionic detergent-soluble (NIDS) proteins from human stratum corneum have been prepared by the combined action of detergent and mechanical stimulation of normal human skin. SDS-polyacrylamide gel electrophoresis studies revealed approximately 15 components falling into the molecular weight ranges of 10,000-15,000, 24,000-37,000, and 44,000-68,000. Immunization of rabbits with this material gave antisera which demonstrated 3 or 4 antigenic components using 2-dimensional immunoelectrophoresis. Studies with 125I-labeled NIDS protein indicated that the main precipitate on 2-dimensional immunoelectrophoresis was associated with SDS-polyacrylamide gel components of molecular weight 15,000 and 30,000. Indirect immunofluorescence studies on human skin sections revealed localization of NIDS protein antigens throughout the suprabasal epidermis but concentrated in the stratum granulosum and stratum corneum. Localization studies using strips of stratum corneum obtained by the skin surface biopsy technique revealed a pericellular type of distribution of the NIDS protein antigens.
