Lysozyme (EP134)

Anti-lysozyme stains myeloid cells, histiocytes, granulocytes, macrophages, and monocytes. It is an important marker that may demonstrate the myeloid or monocytic nature of acute leukemia. The restrictive nature of anti-lysozyme staining suggests that lysozyme may be synthesized predominantly in reactive histiocytes rather than in resting, unstimulated phagocytes. Anti-lysozyme may aid in the identification of histiocytic neoplasias, large lymphocytes, and classifying lymphoproliferative disorders.1-3
