RBM45 solubility during conditions of cellular stress. a Workflow to obtain soluble and insoluble total protein extracts from untreated and stressed HEK293 cells expressing endogenous, N-terminally FLAG-tagged RBM45. “SN” = supernatant. b Western blotting for FLAG-tagged RBM45 (α-FLAG), GAPDH (negative insoluble fraction control), and TDP-43 (positive insoluble fraction control) following sodium arsenite treatment (1 mM for 1 or 2 h). c FLAG-RBM45, GAPDH and TDP-43 solubility following heat shock (1 h at 42 °C)
