Our Abpromise guarantee covers the use of ab106926 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
IHC-P Use a concentration of 3 - 6 µg/ml.
WB Use a concentration of 1 - 3 µg/ml. Detects a band of approximately 110 kDa (predicted molecular weight: 105 kDa).


  • FunctionRNA-binding protein that binds to iron-responsive elements (IRES), which are stem-loop structures found in the 5'-UTR of ferritin, and delta aminolevulinic acid synthase mRNAs, and in the 3'-UTR of transferrin receptor mRNA. Binding to the IRE element in ferritin results in the repression of its mRNA translation. Binding of the protein to the transferrin receptor mRNA inhibits the degradation of this otherwise rapidly degraded mRNA.
  • Sequence similaritiesBelongs to the aconitase/IPM isomerase family.
  • Post-translational
    Ubiquitinated and degraded by the proteasome in presence of high level of iron and oxygen. Ubiquitinated by a SCF complex containing FBXL5. Upon iron and oxygen depletion FBXL5 is degraded, preventing ubiquitination and allowing its RNA-binding activity.

    developed using the ECL technique

    Predicted band size : 105 kDa
    Observed band size : 110 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 60 kDa. We are unsure as to the identity of these extra bands.
  • ab106926 at 3.8 µg/ml staining IREB2 in Human spleen by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections). Steamed antigen retrieval with citrate buffer pH 6 was performed. Antibody was revealed with AP-staining.
