Highly branched HK peptides are effective carriers of siRNA

Abstract

Both the degree of complexity and the sequence specificity are important factors to be considered for developing the HK carrier of siRNA. In particular, we found that certain branched HK polymers (H3K8b, H3K8b(+RGD), and similar structural analogs) with eight terminal branches and a histidine-rich domain were effective carriers of siRNA.
