PAM sequences (green) and the Hpy81 site (purple) used for HMA/restriction digest analysis are shown. b Heteroduplex PCR amplicons from 19 Nf1 G0 animals. c DNA and peptide sequence alignment of the in-frame deletions within Nf1 exon 20. d Heteroduplex PCR amplicons from 19 Nf1 G0 animals were digested with Hpy81 to reveal the presence of smaller indels. No change between the £¿Hpy81 and +Hpy81 indicates the Hpy81 restriction digestion was lost during CRISPR recombination events. e DNA and peptide sequence alignment of the small indels at the 5¡ä and 3¡ä CRISPR target regio %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6117327/
