Overview
The heme protein myeloperoxidase (MPO) is a major component of azurophilicgranules of neutrophils and polymorphonuclear leukocytes. Optimal oxygen-dependent microbiocidal activity depends on MPO as the critical enzyme forthe generation of hypochlorous acid and other toxic oxygen products. TheMPO precursor is synthesized during the promyelocytic stage of myeloid dif-ferentiation and is subsequently processed and transported intracellularly tothe lysosomes. The precursor undergoes cotranslational N-linked glycosyla-tion to produce a glycoprotein. Glucosidases in the endoplasmic reticulum(ER) or early cisGolgi convert the pro-MPO to a form which is sorted into aprelysosomal compartment, which undergoes final proteolytic maturation tonative MPO, a pair of heavy-light protomers. In normal neutrophils, MPO isexpressed as a dimer. Calreticulin, a calcium-binding protein residing in theER, interacts specifically with fully glycosylated apopro-MPO. iMPO mRNA isabundant in human promyelocytic HL-60 and mouse myeloid leukemia NFS-60cells. MPO is expressed at high levels in circulating neutrophils and mono-cytes but is not detectable in microglia, brain-specific macrophages or normalbrain tissue.MPO, which has a molecular weight of approximately 140 kD, is homodimer that can be split into two halves that still have enzymatic activity. These hemi-MPOmonomersconsist of a 59-kD alpha chainand a 13.5-kD beta chain.
This anti-MPO antibody is supplied as Purified (Rabbit, Polyclonal (rabbit origin), Rabbit IgG, kappa, Unconjugated) and is designed to support common target-detection workflows after the on-page specifications.
Key elements and design rationale
- Target: MPO
- Format: Purified
- Localization: Cytoplasmic
- Species reactivity: Human
- Applications (listed): WB, IHC-P
- Conjugate: Unconjugated
- Clone and antibody class: Polyclonal (rabbit origin), Rabbit IgG, kappa
Because antibody performance can depend on epitope context, sample preparation, and biological state, interpret signals using appropriate controls and orthogonal evidence when possible.
Biological background
MPO is referenced in public gene/protein resources (e.g., UniProt and NCBI Gene), which provide curated names/synonyms, protein features, and pathway context. When designing assays, consider potential isoforms, post-translational modifications, and cell-type specific expression that may influence observed signal.
Research relevance and current trends
- Profiling MPO expression across model systems, perturbations, and time points to support mechanistic hypotheses.
- Combining antibody-based detection with multi-omics or imaging readouts to link MPO signal with phenotype.
- Using well-matched controls (isotype controls, genetic perturbations, or independent reagents) to strengthen interpretation of target-associated signal.
Common research applications
- WB
- IHC-P
Use the listed applications as a starting point and tailor experimental design to your sample type and readout requirements.
Notes for experimental interpretation
- Specificity considerations: closely related family members, isoforms, or PTMs can affect apparent specificity; confirm with independent approaches when critical.
- Controls: include negative controls and, when feasible, genetic or pharmacologic perturbations to support target attribution in your system.
- Species and sample context: differences in sequence, expression, fixation, or extraction conditions can change signal behavior across models.
Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
