Fig. 6. Arl1(Q71L) causes massive Brefeldin A (BFA)-resistant Golgi recruitment of COPI coat (ß-COP). Arl1(Q71L) stably transfected CHO cells were treated with 10 µg/ml Brefeldin A for 0 minutes (A-C), 5 minutes (D-F) and 30 minutes (G-I) and then double labeled with a limiting amount of Arl1 antibody to reveal expressed Arl1(Q71L) and with monoclonal antibody against ß-COP. Bars: 10 µm.
