Co-immunoprecipitations between CTCF and endogenous DDX5 and BRG1.
A, anti-CTCF-immunoprecipitated samples were blotted with anti-BRG1 and anti-DDX5 antibodies. Anti-CTCF was used as positive control. Input, 2% of the cell lysate used for immunoprecipitation. B, anti-BRG1-immunoprecipitated samples were blotted with anti-CTCF and anti-DDX5 antibodies. Anti-BRG1 was used as positive control. Input, 2% of the cell lysate used for immunoprecipitation. C, anti-DDX5-immunoprecipitated samples were blotted with anti-CTCF and anti-BRG1 antibodies. Anti-DDX5 was used as positive control. Input, 4% of the cell lysate used for immunoprecipitation.
