Starting from previous methodical approaches a procedure for low temperature methyl methacrylate (MMA) embedding of bone marrow biopsies is introduced, which allows routine application of enzyme and immunohistochemistry without loss of morphological quality by retaining fixation in Schaffer's solution. Survival of enzyme activity and antigen determinants is achieved by washing the fixed specimens in 70% methanol and dehydration in acetone in ascending concentrations at 4 degrees C. Modifications of the plastic embedding technique used in this study simplify and shorten the procedure, so that embedding according to this routine method is complete after two days of preparation. Additionally, a rapid embedding variant is introduced, which enables tissue preparation within one day if necessary. Results are demonstrated using markers for myeloid, lymphoid and epithelial cells as well as immunoglobulins and the proliferation associated antigen Ki-67. The investigation of a panel of monoclonal and polyspecific antibodies in 31 cases shows the eventually reduced immunoreactivity of a few markers after prolonged fixation. As a consequence it seems essential to ensure short fixation periods, especially when the specimens are sent by mail.
