Kinetics of gH2AX formation and elimination in young and senescent Syrian hamster fibroblasts treated with BL. The cells at different passages were treated with 50 µg/ml BL for 30 min, washed with PBS and incubated in BL-free medium for the period of time indicated in the figure. Cell extracts were resolved by SDS-PAGE and analyzed by Western blotting using antibodies specific to gH2AX and beta actin
