Abstract
Paraffin-embedded tissue is prepared removing paraffin from the tissue. The paraffin is removed by generating an electric field effective to produce plasma and direct charged species of the plasma to the paraffin, thereby rendering the paraffin responsive to the electric field. The electric field may move the paraffin out from the tissue due to electrostatic force. Movement of the paraffin may be assisted by moving an electrode utilized to generate the electric field relative to the paraffin. Movement of the paraffin also may be assisted by applying a solvent and/or heat energy to the tissue.
