Human myeloperoxidase (MPO) is a dimeric protein composed of two heavy subunits (53 kDa) and two light subunits (15 kDa).  Each MPO molecule contains two prosthetic porphyrins which play an important role in the catalytic cycle.  Molecular weights for MPO isoforms from pools of normal human samples range from 114,000 to 140,000 daltons reflecting a heterogeneous mixture of isoforms when assayed under non-reducing conditions of SDS-PAGE.  Often MPO from a single donor will yield a homogenous preparation reflecting a single isoform.  The carbohydrate component of MPO, consisting of mannose, glucose and N-acetylglucosamine residues is 2.5%. MPO is inhibited by azide and other compounds.  MPO is stored in primary granules of neutrophils and serves as a bactericidal agent in that MPO catalyzes the production of hypochlorous acid (HOCl), a powerful oxidant.  HOCl is derived from chloride ion (Cl-) and hydrogen peroxide (H2O2).  In a number of inflammatory situations, MPO is released into the extracellular matrix where its measurement can be used as an indication of neutrophil activation.

Myeloperoxidase [Human Leukocytes]
This product is an IgG fraction antibody purified from monospecific antiserum by a multi-step process which includes delipidation, salt fractionation and ion exchange chromatography followed by extensive dialysis against the buffer stated above.  Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-rabbit serum, purified and partially purified Myeloperoxidase [Human Leukocytes].  Cross reactivity against Myeloperoxidase from other tissues and species may occur but have not been specifically determined.

Application Details

This antibody is tested by western blotting suitable for ELISA and immunoprecipitation.  Although not tested, this antibody is likely functional in immunohistochemistry and other immunological methods.  Anti-Human Myeloperoxidase may react with MPO from other sources. Anti-Human Myeloperoxidase detects neutrophilic granulocytes and monocytes in blood and precursors of granulocytes in the bone marrow. This antibody may also detect myeloid leukemias of the bone marrow as well as other sites.
