EAAT3 and xCT are evenly expressed in striatal, hippocampal, and cortical cultures. (A) Western blots of DIV 14 neuronal lysates probed with antibodies against EAAT3 or xCT. EAAT3 or xCT expression was normalized to β-actin, to control for equal protein loading. (B) Quantitation of EAAT3: hippocampal/striatal = 105.08 ± 6.01%, cortical/striatal = 108.95 ± 4.82%. (C) Quantitation of xCT: hippocampal/striatal = 92.75 ± 15.09%, cortical/striatal = 94.97 ± 20.41%. Data shown represent the mean of three experiments.
