Preparation of Isolated Sheets of Human Stratum Corneum

This is the authors' abstract. We don't add key points for this paper.

Summary Methods of preparing intact, undenatured sheets of human stratum corneum are described. The epidermis of split or full-thickness skin is first separated by exposure to ammonia fumes or heat at 60 C. The horny layer is then isolated by incubating in dilute trypsin solution. Cantharidin blisters provide a convenient way of obtaining stratum corneum from living subjects with minimum discomfort and no scarring.
