Fig. 2From: Expression of C-terminal ALK, RET, or ROS1 in lung cancer cells with or without fusionWestern blotting analysis in 37 lung cancer cell lines. The protein expression of ALK, RET, ROS1, KIF5B, or CCDC6 and phosphorylation of ALK, RET, or ROS1 in 37 cell lines was determined by western blotting using the antibodies (Additional file 3: Tables S3). Both actin and COX4 were used as loading controlsBack to article page
