Western blot analysis of Nrf2 concentration in the nuclear and cytoplasmic fractions of K562 cells. Cells were treated with 0.1 mM UPF1 or DPBS (control) for indicated time periods. As a positive control of Nrf2, activation cells were incubated with 0.1 mM H2O2 for 60 min. Then the nuclear and cytoplasmic fractions were separated and analysed for Nrf2 concentration using 10% SDS-polyaclylamide gel. Images were analysed using ImageJ software.
