Used in biomedical research to measure levels of Nuclear Factor Erythroid 2-Related Factor 2 (NrF2) in human biological samples such as serum, plasma, or cell lysates. This ELISA kit enables researchers to quantify NrF2 protein expression for studies related to oxidative stress, inflammation, and cellular defense mechanisms. It is widely applied in investigating diseases where oxidative damage plays a role, including neurodegenerative disorders, cancer, diabetes, and cardiovascular conditions. The assay supports drug development and evaluation of therapeutic agents targeting the NrF2 antioxidant pathway.
