Dissociation of Bach1 and p53 in response to RasV12, DNA damage, and oxidative stress. Pull‐down assays of FLBio‐Bach1 and endogenous p53 in 293T cells in the presence of RasV12 (a), bleomycin (b), and hydrogen peroxide (c). Biotinylated Bach1 was pulled down with streptavidin beads, followed by immunoblotting (IB) analysis with the indicated antibodies.
