The cells were fixed with 1% formaldehyde for 10 min at room temperature and subsequently quenched with 0.125-M glycine. ChIP was performed with anti-Nrf2 antibody (Cell Signaling Technology; D1Z9C).The antibody incubation were pereformed overnight at 4 °C. The DNA libraries were prepared from 2 ng of ChIP and input samples quantified with Qubit Fluorometer (Life Technologies), using Mondrian SP+ and Ovation SP Ultralow DR Multiplex System (TaKaRa).braries were prepared for sequencing using standard Illumina protocols.
