Product Specific Information
The monoclonal antibody 3E4 reacts with human and mouse interferon regulatory factor 4 (IRF4), a 52 kDa transcription factor involved in B cell, T cell, and macrophage function.
- In B cells, IRF4 is highly expressed in mature plasma cells and regulates genes such as Prdm1 (Blimp1).
- In T cells, it contributes to Treg, Th2, Th9, and Th17 cell differentiation and function, and induces Blimp1 and IL-10 expression.
- In macrophages, IRF4 is involved in polarization and immune regulation.
- IRF4 expression is also associated with several blood-related cancers.
Applications Reported: Intracellular staining followed by flow cytometric analysis.
Applications Tested: Tested on stimulated normal human peripheral blood cells using Foxp3/Transcription Factor Buffer Set (Product #00-5523-00) following BestProtocols® for intracellular (nuclear) proteins.
- Recommended use: ≤ 0.125 µg/test (in 100 µL final volume).
- Cell number: 10⁵–10⁸ cells/test (empirically determined).
- Antibody titration recommended for optimal performance.
Excitation: 488–561 nm
Emission: 578 nm
Compatible Lasers: Blue, Green, Yellow-Green
Filtration: 0.2 µm post-manufacturing filtered
Target Information
The IRF (interferon regulatory factor) family contains transcription factors with a tryptophan pentad repeat DNA-binding domain.
- Regulates interferon responses and interferon-inducible genes.
- IRF4 is lymphocyte-specific and negatively regulates TLR signaling, modulating innate and adaptive immunity.
- Chromosomal translocation t(6;14)(p25;q32) involving IRF4 and IgH may cause multiple myeloma.
- Alternative splicing variants have been identified.
