The combination of protease digestion and microwave treatment including the use of heavy metal salts or urea gives an Ig heavy and light chain detection system in formalin\u2010fixed and paraffin\u2010embedded material as good as that achieved using fresh frozen material, with the advantage of a well\u2010preserved morphology. The sensitivity of this method depends on the heavy metal salt used and its concentration. The use of urea yields equally sensitive results, while avoiding the toxicity of heavy metal salts. Heating times in the microwave oven also have an important influence on the results. The microwave\u2010based technique may allow for the improved accessibility of formalin\u2010masked antigens, as was shown here for cytoplasmic and surface immunoglobulins. It was demonstrated that formalin\u2010fixed specimens of Burkitt's lymphoma when subjected to the new protocol almost always showed surface Ig expression, giving results comparable to those obtained in frozen sections. Moreover, it could be shown that in cases of B\u2010chronic lymphocytic lymphoma (B\u2010CLL) or immunocytoma, surface and cytoplasmic Ig could be detected, so that the difference may be just a quantitative one and thus may no longer be safely used as a criterion in differential diagnosis. In future, the wide use of this technique will allow for the study of Ig expression at the single cell level in morphologically well\u2010preserved material.<\/jats:p>","DOI":"10.1002\/path.1711700307","type":"journal-article","created":{"date-parts":[[2005,6,22]],"date-time":"2005-06-22T12:20:28Z","timestamp":1119442828000},"page":"257-264","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":39,"title":["Constant detection of surface and cytoplasmic immunoglobulin heavy and light chain expression in formalin\u2010fixed and paraffin\u2010embedded material"],"prefix":"10.1002","volume":"170","author":[{"given":"Hartmut","family":"Merz","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Olaf","family":"Rickers","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefan","family":"Schrimel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karin","family":"Orscheschek","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alfred C.","family":"Feller","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,6,15]]},"reference":[{"key":"e_1_2_1_2_2","first-page":"18","article-title":"Monoclonal antibodies (MT1, MT2, MB1, MB2, MB3) reactive with leukocyte subsets in paraffin\u2010embedded tissue sections","volume":"127","author":"Poppema S","year":"1987","journal-title":"Am J Pathol"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2559.1989.tb02180.x"},{"issue":"1","key":"e_1_2_1_4_2","first-page":"17","article-title":"Immunophenotyping of hematologic neoplasms in paraffin\u2010embedded tissue sections","volume":"93","author":"Davey FR","year":"1990","journal-title":"Am J Clin Pathol"},{"key":"e_1_2_1_5_2","first-page":"118","article-title":"The aberrancy of immunophenotype and immuno\u2010globulin status as indicators of prognosis in B cell diffuse large cell lymphoma","volume":"133","author":"Spier CM","year":"1988","journal-title":"Am J Pathol"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1093\/ajcp\/95.5.692"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1182\/blood.V65.3.630.630"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1182\/blood.V63.5.1209.1209"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2559.1983.tb02300.x"},{"key":"e_1_2_1_10_2","first-page":"225","article-title":"Detailed phenotypic analysis of B\u2010cell lymphoma using a panel of antibodies reactive in routine fixed wax\u2010embedded tissue","volume":"128","author":"Norton AJ","year":"1987","journal-title":"Am J Pathol"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1136\/jcp.23.3.273"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF01003442"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1179\/his.1983.6.3.125"},{"key":"e_1_2_1_14_2","first-page":"3","article-title":"Use of microwaves for rapid immunoperoxidase staining of paraffin sections","volume":"44","author":"Chiu KY","year":"1987","journal-title":"Med Lab Sci"},{"key":"e_1_2_1_15_2","doi-asserted-by":"publisher","DOI":"10.1177\/39.6.1709656"},{"key":"e_1_2_1_16_2","doi-asserted-by":"publisher","DOI":"10.1182\/blood.V78.5.1311.1311"},{"key":"e_1_2_1_17_2","doi-asserted-by":"publisher","DOI":"10.1177\/32.2.6198355"},{"key":"e_1_2_1_18_2","doi-asserted-by":"publisher","DOI":"10.1177\/27.8.90079"},{"key":"e_1_2_1_19_2","doi-asserted-by":"publisher","DOI":"10.1177\/28.8.6160179"},{"key":"e_1_2_1_20_2","doi-asserted-by":"publisher","DOI":"10.1177\/27.8.90074"},{"key":"e_1_2_1_21_2","doi-asserted-by":"crossref","unstructured":"WernerM v.
