Experiment: Comparing CRISPR/Cas9 gene editing efficiencies between AAV9 and AAVcc47 in Ai9 mice with a 1:3 Cas9 to sgRNA ratio (CMV promoter)
PI: Aravind Asokan, PhD
Description: A dual vector strategy was employed: one delivering two single guide RNAs targeting the Rosa26 locus and one delivering CMV driven SaCas9 (both single stranded AAV cassettes). This strategy was evaluted with both AAV9 (n=4) and AAVcc47 (n=5) by intravenous injection in Ai9 mice. A total dose of 4e12vg was injected into each mouse and vectors mixed in a 1:4 ratio of cas9 to guide RNA (1e12vg of CMV Sacas9 vector and 3e12vg of the sgRNA vector) 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.
