Skin biopsies for immunofluorescence should be sent immediately to Pathology in saline soaked
gauze, or if necessary, may be placed in Michel's fixative (N-ethyl maleimide), available from the
Immunopathology Laboratory (449-4944). The specimen in gauze should be refrigerated as soon
as possible. An H & E section or tissue for light microscopy must accompany tissue sent only for
immunofluorescence.
