The Keap1:Nrf2 Inhibitor Screening Assay Kit is designed for_x000D_identification of inhibitors of Keap1:Nrf2 binding using fluorescence polarization. Using this kit, only one simple step on a microtiter plate is required for_x000D_Keap1:Nrf2 inhibitor screening reactions. The Keap1 protein and fluorescently labeled_x000D_Nrf2 peptide are incubated with a sample containing testing inhibitors for 30 minutes._x000D_The change in fluorescent polarization can then be measured using a fluorescence_x000D_reader.
