Western Blot: ATF6 Antibody (70B1413.1) [NBP1-40256] - Analysis of ATF6. Lane 1, 293 cells transfected with full-length ATF6.* Lane 2, 293 cells transfected with partial length ATF6 (amino acids 1-373).* Lane 3, Untransfected 293 cells. Western blots were probed with 4 ug/ml of the ATF6 monoclonal antibody (20101) and visualized with PicoTect Western Blot Chemiluminescence Substrate (10087K). Film was exposed for 1 min. The top arrow corresponds to the ~90 kDa form of ATF6 described as full-length in the literature. *The human full-length and partial length ATF6 plasmids are described in Luo and Lee (2002).
