Assessment WSLP/NR2B-siRNA cytotoxicity. MTS assays were performed on untransfected PC12 cells and PC12 cells transfected with PEI-siRNA and varying proportions of WSLP/NR2B-siRNA (1 : 1, 2 : 1, 3 : 1, 5 : 1, 10 : 1, or 20 : 1). Error bars represent the standard deviation. Each experiment was repeated 3 times.
