| Research Abstract |
The expression of bcr/abl gene in K562 cells were suppressed to 8.3% at 200nM and 11.6 % at 50nM by siRNA-NES conjugates synthesized solid phase fragment coupling. It was also found that the complex of siRNA and novel peptides (Pfect) was taken up into cells with comparable efficiency to commercially available lipofection reagent. The expression of bcr/abl gene was suppressed to 0.5% by the complex of siRNA-NES conjugate and Pfect. The complex of siRNA and Pfect showed no cyto-toxicity and an intensive resistance against nucleases digestion to extend the half-life time over 48 hours.
