Overview
MPO APC is a Mouse monoclonal targeting MPO, supplied as a APC format for FC workflows. It supports measurement of Human target expression in common experimental systems.
Key elements and design rationale
- Clone: 8/9 — consistent clone identity can support panel reproducibility and cross-study comparisons.
- Isotype: IgG2b, k — informs selection of matched controls and secondary reagents when relevant.
- Conjugate: APC — enables direct detection in fluorescence-based assays.
- Host species: Mouse — useful for panel design and control strategy planning.
- Reactivity: Human — interpret staining in the context of species-specific sequence and expression differences.
Key specifications such as clone identity, isotype, and fluorophore conjugation help researchers align panel design, control selection, and instrument configuration with the biological question and sample type.
Biological background
The clone 8/9, a mouse monoclonal antibody selectively binds with myeloperoxidase (MPO), a glycoprotein present in the granules of myeloid cells. MPO is critical for an optimal oxygen-dependent microbicidal activity of myeloid cells. The MPO generally appears in the myeloblast stage of myeloid cell differentiation. It is the most common functional protein of myeloid cells and is involved in the process of inflammatory immune responses mediated by myeloid cells. The primary translation product of MPO undergoes glycosylation with the production of 89 kDa hemefree apopro-MPO form followed by incorporation of heme and conversion into the enzymatically active pro-MPO form. Subsequently, pro-MPO becomes targeted to azurophil granules where final processing occurs to produce mature dimeric MPO consisting of the 59-64 kDa MPO alpha-chain and the 14 kDa MPO beta-chain. MPO gene expression may serve as an additional marker for subclassification of acute leukemias and may be used to identify leukemic cells arrested at an early stage of the myeloid differentiation pathway.
Research relevance and current trends
- High-parameter immunophenotyping: combining MPO with complementary lineage and activation markers to resolve complex cell states.
- Panel standardization and data comparability: increasing emphasis on consistent reagents, compensation-aware fluorophore choices, and shared gating strategies.
- Integration with single-cell multi-omics: pairing surface marker profiling with transcriptomic or proteomic readouts to connect phenotype to function.
Common research applications
- Flow cytometry: quantify MPO-positive populations and compare expression distributions across conditions or time points.
- Cell sorting: enrich MPO-defined subsets for downstream RNA/protein assays or functional readouts.
Changes in measured signal are typically interpreted in the context of cell subset frequency, activation/differentiation state, and sample processing effects rather than as a standalone readout.
Notes for experimental interpretation
- Fluorophore selection: consider brightness, spectral overlap, and instrument configuration; compensation and spillover can affect apparent population boundaries.
- Biology-driven confounders: activation state, differentiation, and isoform/PTM variation can shift epitope accessibility and apparent expression.
- Control concepts: include matched isotype and fluorescence-minus-one (FMO) controls where appropriate, and interpret results alongside biological positive/negative reference samples.
For antibody-based assays, monoclonal versus polyclonal format can influence epitope recognition breadth and signal consistency. Conjugated antibodies support direct detection and can simplify multicolor panel design when paired with appropriate controls and instrument settings.
