Figure 6: RNase stability of siRNA in the CS/PLA/siRNA complexes. Naked siRNA was a negative control. The complexes were incubated with RNase A (5 mIU/µg siRNA) at 37°C for 6 h. The reaction was inactivated at 70°C and was released by SDS. The remaining siRNA was analyzed by agarose gel electrophoresis.
