MyBioSource is the largest primary manufacturer of Myeloperoxidase (MPO) enzymes for medical research and diagnostic manufacturing globally.

Custom preparations, technical support, bulk quantities and aliquoting available.

Rz is an abbreviation for Reinheitszahl (purity number). It is the ratio of absorbance at 430 nm (heme)/ 280 nm (total protein). It is a measure of the purity of the enzyme. Anything above 0.8 is highly pure.

MPO is a peroxidase enzyme occurs the most in neutrophil granulocytes (a subtype of white blood cells). It is a lysosomal protein stored in azurophilic granules of the neutrophil. Myeloperoxidase has a green heme pigment and is found in pus and some forms of mucus. It is recognized as an important factor in many inflammatory diseases such as cardiovascular and neurological diseases. MPO-specific imaging agents would thus be highly useful to diagnose early disease, monitor disease progression, and quantify treatment effects.

UniProt Comments for Mpo
MPO: Part of the host defense system of polymorphonuclear leukocytes. It is responsible for microbicidal activity against a wide range of organisms. In the stimulated PMN, MPO catalyzes the production of hypohalous acids, primarily hypochlorous acid in physiologic situations, and other toxic intermediates that greatly enhance PMN microbicidal activity. Homodimer; disulfide-linked. Each monomer consists of a light and a heavy chain. Belongs to the peroxidase family. XPO subfamily. 3 isoforms of the human protein are produced by alternative splicing.
