General notes
NRF2 is bound to ubiquitin when it is the nucleus so MW would be higher than cytoplasm.
Please note:
Nrf2 antibody (ab137550) detects no signal in most untreated samples for WB. Stimuli treated samples are recommended. Nrf2 expression is stimulated by oxidative stress, electrophiles and chemical activators (PMID: 25761198, PMID: 27638861 and PMID: 28587109).

Applications
The Abpromise guarantee
Our Abpromise guarantee covers the use of ab137550 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 |
|---|---|---|
| IP |
1/100 - 1/500.
|
|
| ChIP |
Use at an assay dependent concentration.
Assay dependent |
|
| WB | (6) |
1/500 - 1/3000.
Detects a band of approximately 110 kDa (predicted molecular weight: 68 kDa). NRF2 is bound to ubiquitin when it is the nucleus so MW would be higher than cytoplasm. Stimuli treated samples are recommended. Expression levels may be better for nuclear fractions or for cell lines treated with MG132. |
| ICC/IF |
1/100 - 1/1000.
|
|
| IHC-P | (1) |
1/100 - 1/1000. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.

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
