Human cell based directed evolution of adenine base editors with improved efficiency

Application of adenine base editors (ABE) has been precluded by low activity. Here the authors show the generation of a human cell based ABE directional screening system and identification of ABE variant (NG-ABEmax-KR) exhibiting a significant increase in activity for human and mouse genome manipula...

Sumario:Application of adenine base editors (ABE) has been precluded by low activity. Here the authors show the generation of a human cell based ABE directional screening system and identification of ABE variant (NG-ABEmax-KR) exhibiting a significant increase in activity for human and mouse genome manipulation.
