| Abstract: |
In primary cell types, intracellular deoxynucleotide triphosphate (dNTP) levels are tightly regulated in a cell cycle-dependent manner. We report that prime editing efficiency is increased by mutations that improve the enzymatic properties of Moloney murine leukemia virus reverse transcriptase and treatments that increase intracellular dNTP levels. In combination, these modifications produce substantial increases in precise editing rates. Prime editing efficiency is enhanced using a mutated reverse transcriptase and addition of deoxynucleosides. [ABSTRACT FROM AUTHOR] |
