Abstract

Small interfering RNA (siRNA) holds potential as a therapeutic approach to silence targeted gene of disease, but siRNA has limited stability in vivo. Therefore, delivery system of siRNA is the key to siRNA therapeutic application. We have examined bottle brush-type copolymers (BBC) as a long circulation siRNA carrier. In this study, effects of polyethylene glycol)(PEG) brush of BBCs on interaction between siRNA and copolymers were evaluated. As a result, we observed that BBC having higher PEG density shows stronger interaction with siRNA.
