Independent validation of Gong delivery platform using RNP-loaded nanocages to deliver CRISPR/Cas9 to mouse brain |
NC-RVG Females |
On-target editing efficiency was calculated by counting the number of edited Neurons (NeuN+/GFP+ and tdTomato+/RFP+) out of the total number of neurons (NeuN+/GFP+) in a defined region of interest in the brain, expressed as a percentage of neurons in the region of interest (ROI). Off-target editing analysis: peripheral tissues were fixed, cryosectioned and imaged directly for RFP (tdTomato). Presence or absence of signal above background was recorded for each tissue assessed. Biological replicates by condition were as follows: NC-CPP Males: On-target N=3, Off-target N=1; NC-CPP Females: On-target N=3, Off-target N=1; NC-RVG Males: On-target N=3, Off-target N=1; NC-RVG Females: On-target N=3, Off-target N=2; NC No Ligand Male: On-target N=3, Off-target N=2; NC No Ligand Female: On-target N=3, Off-target N=1. *Inconclusive: Signal in cells surrounding epididymal duct/testis germinal epithelium was observed in one animal (1 out of 3-4 tissue sections) |
