摘要：
Paraffin-embedded tissue, which may be disposed on a solid substrate, is prepared by a dry technique that removes paraffin from tissue without adding any liquid to the tissue, thereby rendering the tissue substantially free of paraffin. The dry technique may entail applying heat energy to the tissue effective to melt the paraffin and thereby render it flowable, and applying an electric field. The electric field is effective to impart electrical charge to the paraffin and to move the paraffin out from the tissue due to electrical charge repulsion or attraction, which may be assisted by moving an electrode utilized to generate the electric field relative to the paraffin. The electric field, or both the electric field and the heat energy, may be applied until the tissue is substantially free of paraffin.
