Our Abpromise guarantee covers the use of ab61750 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
WB Use a concentration of 10 µg/ml. Detects a band of approximately 50 kDa (predicted molecular weight: 48 kDa).
Flow Cyt Use 1µg for 106 cells. ab170190-Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.


  • FunctionSpecifically binds to the upstream regulatory region of type I IFN and IFN-inducible MHC class I genes (the interferon consensus sequence (ICS)). Plays a negative regulatory role in cells of the immune system.
  • Tissue specificityPredominantly in lymphoid tissues.
  • Sequence similaritiesBelongs to the IRF family.
    Contains 1 IRF tryptophan pentad repeat DNA-binding domain.
  • Post-translational
    Ubiquitinated. Ubiquitination by TRIM21 in macrophages, a process that is strongly increased upon interferon gamma stimulation, leds to the enhanced transcriptional activity of target cytokine genes.

    Goat polyclonal to Mouse IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution
    developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 48 kDa
    Observed band size : 50 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 13 kDa,17 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 5 minutes
  • Overlay histogram showing K562 cells stained with ab61750 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab61750, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
