Western blot analysis of extracts from COS cells, treated with λ phosphatase or 20% FBS as indicated, using Non-phospho-4E-BP1 (Thr46) (87D12) Rabbit mAb (upper), Phospho-4E-BP1 (Thr37/46) Antibody #9459 (middle), and 4E-BP1 Antibody #9452 (lower).
Confocal immunofluorescent analysis of 293 shRNA Scramble cells either serum starved (far left); serum starved and treated with U0126 #9903 (10 μM, 2 hr), LY294002 #9901 (50 μM, 2 hr), and Rapamycin #9904 (10 nM, 2 hr) (center, left); serum starved and treated with l phosphatase (10,000 U/mL, 2 hr) ) (center, right); and 293 shRNA 4E-BP1/2 KO treated with U0126 #9903 (10 μM, 2 hr), LY294002 #9901 (50 μM, 2 hr), and Rapamycin #9904 (10 nM, 2 hr) (far right), using Non-phospho-4E-BP1 (Thr46) (87D12) Rabbit mAb (green).
