Polyclonal Rabbit Serum E B IP
In normal tissues and in a variety of myeloproliferative disorders, myeloid cells of both neutrophilic and eosinophilic types, at all stages of maturation, exhibit strong cytoplasmic reactivity for MPO. It is readily detected in myeloblasts and immature myeloid cells of acute myelogenous leukemia, progranulocytic leukemia, monomyelocytic leukemia, erythro-leukemia, myeloblastomas, and other hematopoietic disorders. Erythroid precursors, megakaryocytes, lymphoid cells, mast cells, and plasma cells are nonreactive. Cells of monocytic derivation reveal variable reactivity and are typically weakly positive or nonreactive. Cells comprising the infiltrate of a spectrum of lymphoid malignancies, e.g., lymphoblastic lymphoma or leukemia, chronic lymphocytic leukemia, hairy cell leukemia, non-Hodgkin’s lymphomas of T-or B-cell type, and Hodgkin’s disease, are nonreactive, as are the non-neoplastic tissues present in these specimens, except for occasional cells of myeloid derivation. MPO is not observed in the neoplastic cells of a wide variety of epithelial tumors and sarcomas, or in the contiguous non-neoplastic tissues. MPO is useful in differentiating between myeloid and lymphoid leukemias.

ImmunogenMyeloperoxidase (human leukocytes)
SpecificityRecognizes human Myeloperoxidase. Detects neutophilic granulocytes and monocytes in blood and precursors of granulocytes in bone marrow. May also detect myeloid leukemias of the bone marrow as well as other sites. Assay by immunoelectrophoresis resulted in a single precipitin arc against puri ed and partially puri ed Myeloperoxidase (human leukocytes).
