Figure Lengend Snippet: Schematic for CRISPR/Cas9 system into human AAVS1 locus. Top: Human AAVS1 locus. Single guide RNA (sgRNA) is indicated above the AAVS1 locus. Center: Donor DNA with 5’ homology arm (HA) and 3’HA, ∼820 bp on each side (dashed lines), splice acceptor sequence, T2A ribosome-skipping sequences, puromycin resistance sequence, Red Fluorescent Protein sequence (RFP), ancestral uricase sequence (AncUOX), and polyA signal. Bottom: Cas9 cleavage at the cut site allows donor DNA to be integrated via homology directed repair (HDR). After HDR the engineered AAVS1 locus is able to expresses Puromycin-resistance protein, RFP, and AncUOX.
Article Snippet: The pX458 plasmid expressing Cas9 protein, gRNA and GFP were purchased from Addgene (#48138) and digested with Bbs I enzyme (New England Biolabs) .
