Product Description

MA1-20074 detects Myeloperoxidase in human samples. Myeloperoxidase (MPO) is a hemoprotein that is abundantly expressed in neutrophils and secreted during their activation. Native Myeloperoxidase is represented as a covalently bound tetrameric complex of two glycosylated alpha chains with a molecular weight range of 59 - 64 kDa, and two unglycosylated beta chains (MW ~14 kDa) with total MW ~150 kDa and a theoretical pI of 9.2. Traditionally, myeloperoxidase was considered as a main target of anti-neutrophil cytoplasm antibodies (ANCA), the serological markers for certain systemic vasculities such as periarteriitis nodosa, microscopic polyarteriitis and pulmonary eosinophilic granulomatosis (Churg-Strauss syndrome). Low to moderate anti-myeloperoxidase autoantibody levels are also reported in rheumatoid arthritis. Recently, it was shown that myeloperoxidase participates in the initiation and progression of cardiovascular disease. Myeloperoxidase possesses potent proinflammatory properties and may contribute directly to tissue injury. Now Myeloperoxidase is under consideration as one of the most promising cardiac markers. Myeloperoxidase is part of the host defense system of polymorphonuclear leukocytes and myeloperoxidase is responsible for microbicidal activity a
