“… 1 We have also successfully deleted GC-rich regions that are challenging to edit. 11 The common method using a single type of gRNA relies on codon misalignment due to deletions or insertions of a few bases, which may result in the expression of fragmented proteins with initiation codons appearing later than their mutated sites. However, if the large deletions in this method are successful, complete loss of protein expression can be achieved, eliminating these concerns.…”
