Nrf2 Antibody (437C2a) is a mouse monoclonal IgG1 antibody raised against a recombinant protein corresponding to an internal region of Nrf2 of human origin and is recommended for use in western blotting (WB) and immunoprecipitation (IP) applications. Nrf2, a key regulator of the cellular response to oxidative stress, plays a crucial role in maintaining cellular homeostasis by activating the expression of antioxidant and detoxifying enzymes. Nrf2 protein is primarily located in the cytoplasm under normal conditions, where Keap1 maintains regulatory control. Upon exposure to oxidative stress or xenobiotics, Nrf2 is released from Keap1 and translocates to the nucleus, where binding to antioxidant response elements (ARE) in the promoter regions of target genes leads to transcriptional activation. This translocation is vital for the cellular defense mechanism against oxidative damage, as Nrf2 enhances the expression of genes involved in detoxification and antioxidant responses, such as NQO1. The Nrf2 pathway is not only essential for protecting cells from oxidative stress but also plays a significant role in various physiological processes, including inflammation and metabolism, making Nrf2 a critical target for therapeutic interventions in diseases associated with oxidative stress and inflammation. Anti-Nrf2 antibody (437C2a) provides a valuable tool for studying the regulation, localization, and functional dynamics of Nrf2 in oxidative stress-related pathways and cellular processes.

At which band is Nrf2 supposed to appear? is it 40KD (according to the figure) or 61KD (according to the molecular weight)??

Asked by: Khal24
Thank you for your question. The Western blot data published at 40 kDa with this antibody is of a human recombinant Nrf2 fusion protein and is not indicative of the endogenous molecular weight of Nrf2. Please see a useful reference for the molecular weight of Nrf2 below. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3503463/

I am using Nrf2 (437C2a): sc-81342 antibody for immunoprecipitation, how much antibody should I use?

Asked by: TinTin
Thank you for your question. We recommend using 1–10 µl (i.e., 0.2–2 µg) of antibody with 1 ml of cell lysate. However, optimal antibody concentration should be determined by titration.

Rated 2 out of 5 by from Bandas inespecíficasProbé el anticuerpo Nrf2 437C2a en un WB con la línea celular HEPG2,al mismo tiempo que el anticuerpo Nrf2 (A-10): sc-365949. Con el 437C2a aparecen muchas bandas inespecíficas, es mejor el A-10
