Western blot analysis of T-47D and Jurkat cell extracts using ARID1A/BAF250A (D2A8U) Rabbit mAb (upper) or ß-Actin (D6A8) Rabbit mAb #8457 (lower). Additional ARID1A/BAF250A degradation products may be detected in some cell extracts between 135kDa-250kDa, which are absent in the ARID1A/BAF250A negative T-47D cell line.
