Figure 3. DAT protein levels are unchanged in MsrA^−/− mice.

MsrA^−/− and WT cerebral membrane fractions were solubilized and equal amounts of protein were separated by gel electrophoresis followed by western blot analysis. (A) Protein bands detected by anti-DAT antibodies indicate similar amounts of the protein at about 70 kDa. (B) Densitometry values of DAT protein bands are shown as an average density from MsrA^−/− (black) and WT (white) bands (p = 0.69; n = 3 MsrA^−/− and 3 WT mice).
