Specificity
The expression of Nrf2 is stimulated by oxidative stress, electrophiles and chemical activators (PMID: 25761198, PMID: 27638861 and PMID: 28587109). Nrf2 antibody (ab62352) detects no signal in most untreated samples in WB. Stimuli treated samples are recommended. We do not recommend using this product in western blot with tissue lysates, however some customers have used this antibody successfully using concentrated samples (see submitted abreviews).

Target
-
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
modificationsPhosphorylation 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. - Information by UniProt

ab62352 staining Nrf2 in untreated wild type A549 cells (left panel), treated wild type A549 cells (middle panel) and untreated NFE2L2 knockout A549 cells (right panel). Cells were treated with 2µM of MG-132 for 18 hours (ab141003). The cells were fixed with 4% paraformaldehyde (10 min) then permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated with ab62352 at 0.2 µg/ml concentration and ab7291 (Mouse monoclonal to alpha Tubulin) at 1/1000 dilution overnight at 4°C followed by a further incubation at room temperature for 1h with a goat secondary antibody to rabbit IgG (Alexa Fluor® 488) (ab150081) at 2µg/ml (shown in green) and a goat secondary antibody to mouse IgG (Alexa Fluor® 594) (ab150120) at 2µg/ml (shown in magenta). Nuclear DNA was labelled in blue with DAPI.
Image was taken with a confocal microscope (Leica-Microsystems TCS SP8). -

Observed band size: 85 kDa why is the actual band size different from the predicted?False colour image of Western blot: Anti-Nrf2 antibody [EP1808Y] - ChIP Grade staining at 1/500 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (ab8245) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab62352 was shown to bind specifically to Nrf2. A band was observed at 85 kDa in wild-type HeLa cell lysates with no signal observed at this size in NFE2L2 CRISPR-Cas9 edited cell line ab262507 (CRISPR-Cas9 edited cell lysate ab263934). The band observed in the CRISPR-Cas9 edited lysate lane below 85 kDa is likely to represent a truncated form of Nrf2. This has not been investigated further and the functional properties of the gene product have not been determined. To generate this image, wild-type and NFE2L2 CRISPR-Cas9 edited HeLa cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) at 1/20000 dilution.

Predicted band size: 68 kDa
Observed band size: 85-90 kDa why is the actual band size different from the predicted?False colour image of Western blot: Anti-Nrf2 antibody [EP1808Y] - ChIP Grade staining at 1/1000 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (ab8245) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab62352 was shown to bind specifically to Nrf2.
Target band (indicated by arrow) was observed at 85-90 kDa in wild-type A549 cell lysates with no signal observed at this size in NFE2L2 knockout cell line ab285359 (knockout cell lysate ab289682). A band lower than the target was present on both WT and KO, we are unsure about the identity of this band.
To generate this image, wild-type and NFE2L2 knockout A549 cell lysates were analysed. Please note that MG132 treatment does not affect expression levels of Nrf2. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C.
