Western blot analysis of extracts from SK-MEL-28 cells, mock transfected (-) or transfected with scrambled control siRNA (+) or Sox10 specific siRNA (+), using Sox10 Antibody (upper) and GAPDH (D16H11) XP® Rabbit mAb #5174 (lower). The Sox10 specific siRNA confirms Sox10 antibody specificity, while the GAPDH (D16H11) XP® Rabbit mAb is used as a loading control.
