Hapten-binding bispecific antibodies for the targeted delivery of SiRNA and SiRNA-containing nanoparticles

Abstract

Hapten-binding bispecific antibodies (bsAbs) are effective and versatile tools for targeting diverse payloads, including siRNAs, to specific cells and tissues. In this chapter, we provide examples for successful SiRNA delivery using this powerful targeting platform. We further provide protocols for designing and producing bsAbs, for combining bsAbs with SiRNA into functional complexes, and achieving specific mRNA knockdown in cells by using these functional complexes.
