Overview
CD39 PE-Cyanine7 is a Mouse monoclonal targeting CD39, supplied as a PE-Cyanine7 format for FC workflows. It supports measurement of Human target expression in common experimental systems.
Key elements and design rationale
- Clone: CAT-13.0B10 — consistent clone identity can support panel reproducibility and cross-study comparisons.
- Isotype: IgG1, k — informs selection of matched controls and secondary reagents when relevant.
- Conjugate: PE-Cyanine7 — enables direct detection in fluorescence-based assays. Excitation is typically matched to Blue (488nm) lasers in cytometer configurations.
- 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 CAT-13.0B10, a mouse monoclonal antibody recognizes a 70 – 100 kDa cell surface antigen known as CD39. It is also known as ATPDase or Ecto-ATP diphosphohydrolase as it has intrinsic Ecto-ATPase activity. CD39 is expressed on peripheral blood B cells and on a subset of T cells, and its expression level increases upon immune activation. The CD4+ CD39+ T cells catalyze cleavage of adenosine triphosphate (ATP) to adenosine monophosphate (AMP), largely overlap with the CD4+ CD25high FOXP3+ regulatory T cells and mediate potent immune suppression. CD39 also plays an important role in immune activation.
Research relevance and current trends
- High-parameter immunophenotyping: combining CD39 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 CD39-positive populations and compare expression distributions across conditions or time points.
- Cell sorting: enrich CD39-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.
