Additional Information

Swiss-Prot: P05164

Immunogen: Native myeloperoxidase isolated from human leucocytes

Format: Lyophilized

Isotype: IgG  (Matching secondary antibodies)

Description: Myeloperoxidase (MPO) is a heme protein synthesized during myeloid differentiation that constitutes the major component of neutrophil azurophilic granules. Produced as a single chain precursor, myeloperoxidase is subsequently cleaved into a light and heavy chain. The mature myeloperoxidase is a tetramer composed of 2 light chains and 2 heavy chains. This enzyme produces hypohalous acids central to the microbicidal activity of netrophils. SUBCELLULAR LOCATION: Lysosome Also known as: MPO.

Specificity: Appears to be specific for MPO.

Application Details

Application Notes: IHC, WB. A working concentration of 10-50 µg/ml is recommended. The optimal dilution should be determined by the end user. This antibody performs superbly in paraffin-embedded tissue sections fixed in formalin, frozen sections and cell cytospins.

Purity: IgG

Storage: Maintain the lyophilised/reconstituted antibodies frozen at -20°C for long term storage and refrigerated at 2-8°C for a shorter term. When reconstituting, glycerol (1:1) may be added for an additional stability. Avoid freeze and thaw cycles.

Research Area: Enzymes, Metabolism, Immunology

Restrictions: For Research Use only

Images

Isolated monocytes were stained with Lysotrack red followed by staining with Rabbit antibody to human myeloperoxidase (MPO): IgG (3µg/ml) for 1 hour at room temperature, washed and  followed by staining with goat anti-rabbit antibody conjugated to Alexa 488 (Green) for 1 hr. Mounting media (10% Glycerol in PBS) containing Hoechst 33258 1 µg/ml (Sigma-Aldrich) was used for nuclear counterstaining (Blue).  Fluorescent cell staining was analysed by confocal microscopy using a BioRad Radiance 2100 confocal microscope. Magnification: 80X

10 µg of neutrophil lysate was separated by 12% SDS-PAGE. Proteins were transferred onto a PVDF membrane and blocked by incubation with PBS containing 2% skim milk and 0.02% Tween 20 for 30 min. Membranes were probed with Rabbit antibody to human myeloperoxidase (MPO): IgG (3 µg/ml) for 1 hr. Membranes were then probed with goat anti-rabbit antibody conjugated to alkaline phosphatase diluted 1:1000 and developed with ECF luminescence substrate (Amersham Biosciences).
