Myeloperoxidase is a heme protein used by granulocytes producing hypohalous acids central during phagocytosis of microbial particles engulfed. Myeloperoxidase (MPO) expression has been observed by strong immunoreactivity to anti Myeloperoxidase antibodies at all stages of maturation in mormal cells of myeloid origin, and and in a variety of myeloproliferative disorders of myeloid cells. Erythroid precursors, megakaryocytes, lymphoid cells, mast cells, and plasma cells are nonreactive for anti Myeloperoxidase antibodies. MPO is not observed in the neoplastic cells of a wide variety of epithelial tumors and sarcomas. Anti MPO is useful in distinguishing between myeloid and lymphoid leukemias.
