Western blot analysis of extracts from HeLa cells, transfected with 100 nM SignalSilence ® Control siRNA (Unconjugated) #6568 (-), SignalSilence ® Fatty Acid Synthase siRNA I (+), or SignalSilence ® Fatty Acid Synthase siRNA II #12613 (+), using Fatty Acid Synthase (C20G5) Rabbit mAb #3180 (upper) or β-Actin (D6A8) Rabbit mAb #8457 (lower). The Fatty Acid Synthase (C20G5) Rabbit mAb confirms silencing of fatty acid synthase expression, while the β-Actin (D6A8) Rabbit mAb is used as a loading control.
