Experiment: Comparing CRISPR/Cas9 gene editing efficencies between AAV9 and AAVcc47 in Ai9 mice with a 1:1 Cas9 to sgRNA ratio (CB promoter)
PI: Aravind Asokan, PhD
Description: A dual vector strategy was employed: one delivering a single guide RNA and CB driven SaCas9, and another delivering the second guide RNA and CB driven SaCas9. This strategy was evaluted with both AAV9 (n=4) and AAVcc47 (n=5) by intravenous injection in Ai9 mice. A total dose of 2e12vg was injected into each mouse (1e12vg each vector mixed 1:1) and organs were harvested 4 weeks post injection. Editing efficency was determined by calculating percent TdTomato+ cells normalized to Dapi+ cells in liver and heart.
Editing Assay:
Editing efficiency calculated by counting fluorescent cells (TdTomato) compared to DAPI stained cells.
