Description: The monoclonal antibody MNGPKL reacts with mouse interferon regulatory factor 7 (IRF7), a 54 kDa transcription factor essential for induction of the antiviral innate immune response and IFN alpha production. B cells, plasmacytoid dendritic cells (pDC), and monocytes constitutively express IRF7 in the cytoplasm until activation by viral infection, double-stranded RNA or Toll-like receptor (TLR) signaling. CpG ODNs and single-stranded RNA, recognized by CD289 (TLR9) and TLR7, respectively, trigger IRF7 activation and upregulation. This activation promotes type I IFN response to disrupt pathogen and viral infection. These events cause IRF7 phosphorylation and translocation to the nucleus where it forms a homodimer to affect transcription.
Applications Reported: This MNGPKL antibody has been reported for use in intracellular staining followed by flow cytometric analysis.
Applications Tested: This MNGPKL antibody has been tested by intracellular staining and flow cytometric analysis of stimulated mouse splenocytes using the Intracellular Fixation and Permeabilization Buffer Set (cat. 88-8824) and protocol. Please refer to Best Protocols: Protocol A: Two step protocol for (cytoplasmic) intracellular proteins located under the Resources Tab online. This can be used at less than or equal to 0.25 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser.
Filtration: 0.2 µm post-manufacturing filtered.
Interferons (IFNs) are involved in a multitude of immune interactions during viral infections and play a major role in both the induction and regulation of innate and adaptive antiviral mechanisms. During infection, host-virus interactions signal downstream molecules such as transcription factors such as IFN regulatory factor-3 (IRF3) which can act to stimulate transcription of IFN-a/b genes. IRF7 has been shown to play a role in the transcriptional activation of virus-inducible cellular genes, including interferon beta chain genes. IRF7 play a major role in the innate immune pathway, interacting with the Toll-like receptor (TLR) adaptor proteins MyD88 and Tirp/TRAM and functioning as an intermediate TLR4 and TLR9 signaling. There are at least four differentially spliced isoforms of IRF7, although their function has not been clearly established.
