Protein interactions between WT1 and p53 but not p63 by co-IP. Equivalent amounts of protein lysate from FaDu cells were incubated with the anti-WT1, anti-IgG antibodies, followed by incubation with Protein G Sepharose 4 Fast Flow. Immunoprecipitated proteins were analyzed by Western blotting. Immuno-blotting was conducted using anti-WT1, p53 and p63.
