966-QuadPE: Platform for Large Genomic Insertions

Paper Talk · May 14, 2026 · 25m

The study presents QuadPE, a novel prime editing platform designed for the efficient and precise insertion of large DNA fragments into the genome. Unlike traditional methods that rely on double-stranded breaks or complex integrases, this system uses four strategically coordinated pegRNAs to guide donor DNA into specific genomic loci. Researchers demonstrated that QuadPE can integrate payloads ranging from 1.6 to 26 kilobases with significantly higher success rates than existing recombinase or transposase-mediated technologies. The platform proved effective across various cell types, achieving…
