title: [Microwave oven in immunohistochemistry. An important tool for determination of antigens in formalin-fixed and paraffin-embedded tissue].
abstract: Immunocytochemical methods are important tools for identifying antigens in tissue sections and cell smears. Some antigens were retrieved in formalin-fixed and paraffin-embedded tissues by means of a microwave technique. This method also increased the sensitivity of the immunohistochemical detection of several other antigens. Altogether, microwave boiling of the tissue sections in citrate buffer clearly improved the immunoreactivity for cytokeratin 18, oestrogen receptor, Ki-67 protein, PCNA, p53 protein, retinoblastoma gene protein and c-erbB-2 protein. This new technique, which can be applied in every pathology laboratory, will facilitate the application of immunohistochemical methods for research and diagnostic work.
