Our Abpromise guarantee covers the use of ab3428 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
  • Application notesWB: Use at a concentration of 0.5 - 2 µg/ml. Detects a band of approximately 47 kDa in K562 lysate(predicted molecular weight: 47 kDa).

    Not yet tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • 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.
