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 & 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. IRF7 encodes interferon regulatory factor 7, a member of the interferon regulatory transcription factor (IRF) family. IRF7 has been shown to play a role in the transcriptional activation of virus-inducible cellular genes, including interferon beta chain genes. Inducible expression of IRF7 is largely restricted to lymphoid tissue. Multiple IRF7 transcript variants have been identified, although the functional consequences of these have not yet been established.
