IP-MS/MS identification of ARID1A-interacting proteins. A Cellular proteins immunoprecipitated by isotype IgG or anti-ARID1A antibody were resolved by SDS-PAGE and visualized with Oriole fluorescence gel stain. B Immunoblotting revealed a distinct ARID1A protein band at approximately 250 kDa in the anti-ARID1A-IP sample. C nanoLC-ESI-LTQ-Orbitrap MS/MS analysis confirmed that the 250 kDa-immunoreactive band was ARID1A
