Detection of Human Myeloperoxidase/MPO by Western Blot. Western blot shows lysates of HL-60 human acute promyelocytic leukemia cell line and human neutrophil. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human Myeloperoxidase/MPO Monoclonal Antibody (Catalog # MAB3174) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Myeloperoxidase/MPO at approximately 65 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.

Myeloperoxidase/MPO was detected in immersion fixed paraffin-embedded sections of human spleen using 15 µg/mL Mouse Anti-Human Myeloperoxidase/MPO Monoclonal Antibody (Catalog # MAB3174) overnight at 4 °C. Before incubation with the primary antibody tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained with the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue).

Myeloperoxidase/MPO in Mouse Spleen. Myeloperoxidase/MPO was detected in immersion fixed paraffin-embedded sections of mouse spleen using Mouse Anti-Human Myeloperoxidase/MPO Monoclonal Antibody (Catalog # MAB3174) at 10 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (VC001). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (CTS013). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in lymphocytes. Staining was performed using our protocol for IHC Staining with VisUCyte HRP Polymer Detection Reagents.

Background: Myeloperoxidase/MPO
Myeloperoxidase (MPO) is a hemeprotein that belongs to the XPO subfamily of the heme peroxidase superfamily. MPO is synthesized as a preproprotein that undergoes proteolytic processing to generate a disulfide-linked heterodimer of the N-terminal beta -subunit (12 kDa) and C-terminal alpha subunit (60 kDa). Active MPO is a tetramer of two beta -subunits and two alpha -subunits that are also disulfide-linked through the two alpha -subunits. MPO is stored in granules and is an abundant protein in neutrophils and monocytes. MPO is released upon activation to catalyze the formation of powerful oxidants such as hypochlorous acid, which kills microbes. Unprocessed pro-MPO can also be released. Human and mouse MPO share 87% amino acid sequence identity.

This antibody does not stain Neutrophil Extracellular Traps (NETs) on coverslips, whereas it does stain intracellular MPO. This raises questions about its specificity. This antibody is also not reactive in a sandwich ELISA to detect NETs, despite the fact that MPO is known to be a very abundant protein on NETs... On western blot it does detect a protein at the right molecular weight already at low concentrations.
