WB Use a concentration of 1 µg/ml. Predicted molecular weight: 68 kDa.
ELISA Use at an assay dependent concentration.


  • Function
    Transcription activator that binds to antioxidant response (ARE) elements in the promoter regions of target genes. Important for the coordinated up-regulation of genes in response to oxidative stress. May be involved in the transcriptional activation of genes of the beta-globin cluster by mediating enhancer activity of hypersensitive site 2 of the beta-globin locus control region.
  • Tissue specificity
    Widely expressed. Highest expression in adult muscle, kidney, lung, liver and in fetal muscle.
  • Sequence similarities
    Belongs to the bZIP family. CNC subfamily.
    Contains 1 bZIP domain.
  • Domain
    Acidic activation domain in the N-terminus, and DNA binding domain in the C-terminus.
  • Post-translational
    Phosphorylation of Ser-40 by PKC in response to oxidative stress dissociates NFE2L2 from its cytoplasmic inhibitor KEAP1, promoting its translocation into the nucleus.
  • Cellular localization
    Cytoplasm > cytosol. Nucleus. Cytosolic under unstressed conditions, translocates into the nucleus upon induction by electrophilic agents.

  • Anti-Nrf2 antibody (ab89443) at 1 µg/ml + PC12 cell lysate at 50 µg

    Predicted band size: 68 kDa
    Observed band size: 68 kDa

  • ICC/IF image of ab89443 stained HeLa cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 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 (ab89443, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96879, DyLight® 488 goat anti-mouse 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.

  • IHC image of Nrf2 staining in Human Lung formalin fixed paraffin embedded tissue section, performed on a Leica Bond™ system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab89443, 0.5 µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.


    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

  • Overlay histogram showing HepG2 cells stained with ab89443 (red line). The cells were fixed with 4% paraformaldehyde (10 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 (ab89443, 0.5µg/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 IgG2a [ICIGG2A] (ab91361, 1µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in HepG2 cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

  • Anti-Nrf2 antibody (ab89443) at 1 µg/ml + recombinant immunogen at 0.2 µg

    Predicted band size: 68 kDa
    Observed band size: 37 kDa (why is the actual band size different from the predicted?)

    Western blot against tagged recombinant immunogen using ab89443 antibody at 1µg/ml dilution. Predicted band size of immunogen is 11kDa.
