Species cross-reactivity is determined by western blot.

Applications Key: F=Flow Cytometry,

Specificity / Sensitivity

NRF2 (D1Z9C) XP® Rabbit mAb (Alexa Fluor® 488 Conjugate) recognizes endogenous levels of total NRF2 protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala275 of human NRF2 protein.


This Cell Signaling Technology antibody is conjugated to Alexa Fluor® 488 fluorescent dye and tested in-house for direct flow cytometric analysis in mouse cells. This antibody is expected to exhibit the same species cross-reactivity as the unconjugated NRF2 (D1Z9C) XP® Rabbit mAb #12721.

Flow Cytometry

Flow Cytometry

Flow cytometric analysis of MEF cells, untreated (blue) or treated with MG-132 #2194 (10 μM, 10 hr; green), using NRF2 (D1Z9C) XP® Rabbit mAb (Alexa Fluor® 488 Conjugate).


The nuclear factor-like 2 (NRF2) transcriptional activator binds antioxidant response elements (ARE) of target gene promoter regions to regulate expression of oxidative stress response genes. Under basal conditions, the NRF2 inhibitor INrf2 (also called KEAP1) binds and retains NRF2 in the cytoplasm where it can be targeted for ubiquitin-mediated degradation (1). Small amounts of constitutive nuclear NRF2 maintain cellular homeostasis through regulation of basal expression of antioxidant response genes. Following oxidative or electrophilic stress, KEAP1 releases NRF2, thereby allowing the activator to translocate to the nucleus and bind to ARE-containing genes (2). The coordinated action of NRF2 and other transcription factors mediates the response to oxidative stress (3). Altered expression of NRF2 is associated with chronic obstructive pulmonary disease (COPD) (4). NRF2 activity in lung cancer cell lines directly correlates with cell proliferation rates, and inhibition of NRF2 expression by siRNA enhances anti-cancer drug-induced apoptosis (5).
