Validating Traffic Light Reporter 7 (TLR7) Mouse Model for NHEJ in Heterozygous Blastocysts
|
WT female mouse and homozygous male mouse containing the Traffic Light Reporter 7 (TLR7) reporter at the Rosa26 locus were mated. Females were super-ovulated and zygotes harvested. Zyotes were electroporated with Cas9 RNP along with test guides and were cultured 96 hours to blastocyst stage. Blastocysts were imaged for Katushka2S (RFP) fluorescence and scored for fluorescence signal. Blastocysts were then PCR amplified for the reporter allele and Sanger sequenced. ICE analysis tool from Synthego was used to score edits. NOTE: Some blasts did not PCR amplify well and it could not be determined if they had edits. Total blasts analyzed expressing the fluorescent reporter, 169. Total blast analyzed by Sanger sequencing, 117. |

Independent validation of Chaikof delivery platform using virus-like particle (VLP) delivery to the mouse liver
|
Virus-like particles carrying a CRISPR/Cas base editor and a guide RNA targeting the PSCK9 locus were injected i.v. into male and female mice. One week after injection, the mice were dissected, and genomic DNA isolated from a panel of organs. Targeted NGS was performed to evaluate the degree of editing at the PCSK9 locus in the liver (primary target), and non-target organs. Two potential off-target editing sites (OT6 and OT7) were also sequenced. |
