vPE
Also known as: next-generation prime editor, very-precise prime editor
Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Combining this error-suppressing strategy with the latest efficiency-boosting architecture, we design a next-generation prime editor (vPE). Compared with previous editors, vPE features comparable efficiency yet up to 60-fold lower indel errors, enabling edit:indel ratios as high as 543:1.
Usefulness & Problems
No literature-backed usefulness or problem-fit explainer has been materialized for this record yet.
Published Workflows
Objective: Engineer a next-generation prime editor with minimal genomic errors while maintaining editing efficiency.
Why it works: The workflow is based on the observation that promoting nicked end degradation is consistent with destabilizing the competing 5' strand, which should reduce the strand-retention bias that hinders prime editing efficiency and causes indel errors.
