TL;DR

It is shown that an optimized single-guide RNA scaffold architecture improves RNP stability, and when combined with additional EV engineering leads to a three-hundred-fold increase in potency, enabling efficient base editing or knockout in primary cells, human brain organoids and in vivo, including the mouse brain.
