Western blot analysis of extracts from HeLa cells, transfected with 100 nM SignalSilence ® Control siRNA (Unconjugated) #6568 (-), SignalSilence ® EGF Receptor siRNA I (+) or SignalSilence ® EGF Receptor siRNA II #6482 (+), using EGF Receptor (D38B1) XP ® Rabbit mAb #4267 and α-Tubulin (11H10) Rabbit mAb #2125. The EGF Receptor (D38B1) XP ® Rabbit mAb confirms silencing of EGF Receptor expression, while the α-Tubulin (11H10) Rabbit mAb was used to control for loading and specificity of EGF Receptor siRNA.
