Myeloperoxidase/MPO was detected in immersion fixed paraffin-embedded sections of human spleen using 3 µg/mL Goat Anti-Human/Mouse Myeloperoxidase/MPO Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3667) 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-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Detection of Human/Mouse Myeloperoxidase/MPO by Western Blot.
Western blot shows lysates of HL‑60 human acute promyelocytic leukemia cell line, human neutrophil cells, and mouse spleen tissue. PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human/Mouse Myeloperoxidase/MPO Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3667) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for Myeloperoxidase/MPO at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.
Detection of Mouse Myeloperoxidase/MPO by Simple WesternTM.
Simple Western lane view shows lysates of mouse spleen tissue, loaded at 0.2 mg/mL. A specific band was detected for Myeloperoxidase/MPO at approximately 67 kDa (as indicated) using 5 µg/mL of Goat Anti-Human/Mouse Myeloperoxidase/MPO Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3667) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.
Myeloperoxidase/MPO was detected in immersion fixed mouse splenocytes using Goat Anti-Human/Mouse Myeloperoxidase/MPO Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3667) at 15 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

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. Mouse MPO shares 87% amino acid sequence identity with that of human MPO.
