Experiment: Pcsk9 adenine base editor efficiency in liver and nonliver tissue
PI: Elliot L. Chaikof, MD, PhD
Description: Adenine base editing at the Pcsk9 exon 1 splice donor site in mouse heart, kidney, liver, lungs, muscle, and spleen was assessed one week after systemic administration of an adenine base editor delivered by engineered virus-like particles (BE-eVLPs) in C56BL/6 mice
  
  
  
  Editing Assay:
