Abstract
Immunohistochemistry of trephine bone marrow biopsies plays a prominent role in diagnostic assessment of a broad spectrum of non-neoplastic and neoplastic hematologic and metastatic diseases. We tested the quality of immunohistochemical stainings in sections of methyl-methacrylate-embedded core biopsies prepared according to the so-called Hannover-method of cold polymerization using the novel biotin-free tyramide signal amplification system in comparison to the alkaline phosphatase-conjugated "EnVision" method. Examining a large panel of immunohistochemical markers, the amplification system proved to be a highly sensitive technique substantially superior to the EnVision-AP method in reliably detecting the antigenic determinants of the target cells and referred to the intensity of immunoprecipitations.
