Methods: HEK293T cells (0.2 million cells) were transfected with 1 μg PE2/PE3 mRNA, 30pmol nicking sgRNA and 90pmol pegRNA of different lengths (HPLC grade) targeting the HEK3 gene, via electroporation. Genome DNA was then extracted 3 days post-transfection for editing efficiency analysis via Sanger sequencing.
Results: pegRNA with a tevopreQ1 motif achieved editing efficiencies as high as 43.4%, which was significantly higher than that of the pegRNA without the tevopreQ1 motif.
Note: the 218 nt pegRNA is an extended version of 181 nt with a tevopreQ1 motif (37 nt) at the 3’ end. It has been reported that adding the RNA structural motifs evopreQ1 or mpknot to the 3’ end of a pegRNA can protect the 3’ end from exonuclease digestion (Nelson, J. W. et al., 2022).
Methods: 0.2 million HEK293T cells were transfected with different dosages of 141 nt long pegRNA (desalt or HPLC purified grade) targeting the HEK3 gene, via electroporation. Nicking sgRNA was also added in a ratio of 3:1 to pegRNA. PE2/PE3 mRNA was added with increasing dosages from 0.15 μg, 0.25 μg, 0.5 μg, 0.75 μg, 1.0 μg to 1.5 μg. Genome DNA was then extracted 3 days post-transfection for editing efficiency analysis via Sanger sequencing.
Results: Editing efficiencies up to 52.5% for desalt and 63.5% for HPLC-purified pegRNA was achieved. Editing efficiency increased in a dose-dependent manner.
Methods: HEK293T cells (0.2 million cells) were transfected with a 1 μg pCMV-PE2/PE3 plasmid and 45pmol of 141 nt long pegRNA targeting the HEK3 gene, via electroporation. Genome DNA was then extracted 3 days post-transfection for editing efficiency analysis via Sanger sequencing. 15pmol of additional nicking sgRNA was added to direct the prime editor enzyme to nick the non-edited strand in the PE3 system.
Results: GenScript’s HPLC grade and desalt pegRNA achieved comparable editing efficiency to Vendor I with more cost-effective price.
