Fig. 8. Immunoprecipitation experiments. Cells lysates were immunoprecipitated with anti-Rb (lane 2), anti-p53 (lane 5) and control IgG (lanes 3 and 6). The immunoprecipitates were resuspended in a 2x Laemmli sample buffer and western blots were performed to detect Brg1. Lanes 1 and 4, input protein lysates.
