Abstract

Precise, on-target CRISPR-Cas9 genome editing has been shown in Schistosoma mansoni, involving both non-homology end joining and homology-directed repair pathways. Here, we present a multiplexed CRISPR-Cas9 protocol for large transgene integration into the S. mansoni genome. We describe steps for deploying multiplexed ribonucleoprotein complexes (RNPs) and donor DNA preparation. We then detail procedures for introducing RNPs into schistosome eggs by square-wave electroporation in the presence of a 5' phosphorothioate-modified double-stranded donor transgene. For complete details on the use and execution of this protocol, please refer to Ittiprasert et al. (2023)..
