Properties

Applications

Our Abpromise guarantee covers the use of ab62505 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ICC/IF Use a concentration of 5 µg/ml.
WB Use a concentration of 0.5 - 2 µg/ml. Detects a band of approximately 51 kDa (predicted molecular weight: 54 kDa).Can be blocked with Human IRF7 peptide (ab92594).
IP Use at an assay dependent concentration.
IHC-P Use a concentration of 5 µg/ml.

Target

  • Function
    Transcriptional activator. Binds to the interferon-stimulated response element (ISRE) in IFN promoters and in the Q promoter (Qp) of EBV nuclear antigen 1 (EBNA1). Functions as a molecular switch for antiviral activity. Activated by phosphorylation in response to infection. Activation leads to nuclear retention, DNA binding, and derepression of transactivation ability.
  • Tissue specificity
    Expressed predominantly in spleen, thymus and peripheral blood leukocytes.
  • Sequence similarities
    Belongs to the IRF family.
    Contains 1 IRF tryptophan pentad repeat DNA-binding domain.
  • Post-translational
    modifications
    In response to a viral infection, phosphorylated on the C-terminal serine cluster. Phosphorylation, and subsequent activation is inhibited by vaccinia virus protein E3.
    TRAF6-mediated ubiquitination is required for IRF7 activation.
  • Cellular localization
    Nucleus. Cytoplasm. The phosphorylated and active form accumulates selectively in the nucleus.

Anti-IRF7 antibody images

  • ICC/IF image of ab62505 stained HepG2 cells (ab7900). The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum (ab7481) / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab62505, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

    Predicted band size : 54 kDa
    Observed band size : 51 kDa (why is the actual band size different from the predicted?)
  • Immunohistochemistry of IRF7 in paraffin embedded mouse spleen tissue section with ab62505 antibody at 5 µg/ml.
  • IRF7 was immunoprecipitated using 0.5mg Jurkat whole cell extract (ab7899), 5µg of Rabbit polyclonal to IRF7 and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
    The antibody was incubated under agitation with Protein G beads for 10min, Jurkat whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab62505.
    Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697).
    Band: 49kDa: IRF7; non specific - 40kDa: We are unsure as to the identity of this extra band.
