title: Microwave irradiation for rapid epidermis-dermis separation and improved epidermal cell immunodetection.
abstract: We explored the effects of microwave irradiation on epidermal-dermal separation and subsequent immunostaining of epidermal cells. Epidermal sheets were obtained after incubation in 0.02 M EDTA in PBS and microwave irradiation with 4 pulses of 420 watts for 5 sec, with a total incubation period of 4 min. The control epidermal sheets were immunostained for Langerhans cells and dendritic epidermal T cells using a conventional immunoperoxidase method. The experimental immunodetection of these cells was assisted by incubating the primary antibodies for 10 min at 70 watts. We showed a simple and rapid method for separation of the epidermal-dermal junction and immunostaining of epidermal cells with optimal morphological preservation.
