Recombinant Human MPO Protein (Met1-Ser745), His-tagged

Cat.No. : MPO-527H
Product Overview : Recombinant Human MPO Protein (NP_000241.1) (Met1-Ser745) was produced by Baculovirus-Insect Cells expression system. This protein was expressed with a polyhistidine tag at the C-terminus.
Description : MPO (myeloperoxidase) is a peroxidase enzyme secreted by activated leukocytes that plays a pathogenic role in cardiovascular disease, mainly by initiating endothelial dysfunction.Myeloperoxidase (MPO) is an important enzyme, which is one of the components of the antibacterial system in neutrophils and monocytes. MPO participates in the inflammatory response in multiple locations in the body, including the mammary glands.Myeloperoxidase (MPO), a specific polymorphonuclear leukocyte enzyme, has been used previously to quantify the number of neutrophils in tissue. MPO activity was found to be linearly related to the number of neutrophil cells.The MPO system plays an important role in the control of infections and the deletion of malignant cells. Nevertheless, alternations in the MPO system can lead to DNA damage and carcinogenesis. Polymorphisms in the MPO Gene have been associated with an increased expression of MPO and a higher risk for development of cancer.Myeloperoxidase (MPO) is one of the major target antigens of antineutrophil cytoplasmic autoantibodies (ANCA) found in patients with small-vessel vasculitis and pauci-immune necrotizing glomerulonephritis.Myeloperoxidase-anti-neutrophil cytoplasmic antibody (MPO-ANCA) is an autoantibody that is frequently found in patients with vasculitides.

Form : Lyophilized from sterile 20 mM Tris, pH 8.0, 500 mM NaCl, 10 % glycerol. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Molecular Mass : The recombinant human MPO consists of 708 amino acids and predicts a molecular mass of 80.4 kDa.
Protein length : Met1-Ser745
Endotoxin : < 1.0 EU per μg protein as determined by the LAL method.
Purity : > 90 % as determined by SDS-PAGE.
Stability : Samples are stable for up to twelve months from date of receipt at -70 centigrade.
Storage : Store it under sterile conditions at -20 centigrade to -80 centigrade. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 mg/ml. Centrifuge the vial at 4ºC before opening to recover the entire contents.
Shipping : In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
