  1. * The levels of the exogenous hTDP-43 proteins relative to the endogenous mTDP-43 were measured first by Western blot analysis using the Gene Tex antibody recognizing both hTDP-43 and mTDP-43. The ratio of the intensity of the exogenous hTDP-43 to that of the endogenous mTDP-43 at each dose of the transfection was estimated and then calibrated against the average transfection efficiencies of the cells (50% for NSC34 and 70% for Neuro2a cells).
