Normally, cellular responses to modified siRNAs or new siRNA delivery systems have been studied in group cell behavior by PCR, western blotting and fluorescence microscopy. In this study, we present a novel high-content screening (HCS) strategy to evaluate a novel delivery system (named CLD) of siRNA therapeutics, with which both the content of intracellular siRNAs and changes in protein expressing levels have been quantified in group cells and cellular population. We also observed that with the better cell uptake, CLD provided siRNA therapeutics (siBraf) better antitumor capability. This novel strategy was proved to be with efficiency, accuracy and high competency to adherent cell lines, thus making siRNA research more simplified. 展开更多
