Disc-electrophoretic separation of water soluble proteins from scales of different forms of ichthyosis.
In extracts of scales of different forms of ichthyosis, disc-electrophoretic separation of water soluble proteins was performed. Number and position of the protein bands correspond with number and position of the bands of extracts of normal keratin and psoriatic scales. However, in comparison to normal keratin, all examined forms of ichthyosis showed in zone II the enriched bands Nos. 6 and 7. This permits a distinct differentiation from psoriasis in which in zone II the bands Nos. 9 and 10 are enriched. In congenital ichthyosiform erythroderma and in ichthyosis combined with atopic dermatitis, in zone III the bands, containing gamma globulins, are enriched as an expression of the concomittant exudative process. The protein content of scale extracts of ichthyosis is 2 to 5 times lower than the one of psoriasis.
