COMBI IC Reagent: Mouse anti Myeloperoxidase-C2 (FITC) and Mouse anti CD22 (PE)

Myeloperoxidase (MPO) is a glycoprotein present in the azurophil (primary) granules of myeloid cells, which appears in the myeloblast stage of myeloid cell differentiation. MPO is he most common functional protein of myeloid cells and is involved in the inflammatory response. It helps to kill microbes by breaking down peroxide in the presence of halide ions, contributing to the bactericidal function of granulocytes. The primary translation product of MPO undergoes glycosylation with production of the 89 kDa heme-free apopro-MPO form followed by incorporation of heme and conversion into the enzymatically active pro-MPO form. Subsequently, pro-MPO becomes targeted to azurophil granules where final processing occurs to produce mature dimeric MPO consisting of the 59-64 kDa MPO α-chain and the 14 kDa MPO β-chain. Precursor B-cells are surface-CD22 negative, but cytoplasmic CD22 positive. Mature B-lymphocytes.express CD22 also on their surface. The combined staining for MPO and CD22 allows the distinction of mature/immature myeloid cells and B-lymphocytes. The MPO-C2/CD22 COMBI-IC mAb permits the identification and enumeration of normal and malignant myelomonocytic cells and B lymphoid commited cells in human blood and bone marrow using flow cytometry. Results must be put within the context of other diagnostic tests as well as the clinical history of the patient by a certified professional before final interpretation. Analyses performed with this antibody should be paralleled by positive and negative controls. If unexpected results are obtained which cannot be attributed to differences in laboratory procedures, please contact us.
