WebThe first step of T7E1-mediated validation is to harvest genomic DNA and amplify the region surrounding the gRNA target site by PCR ( Table 1 ). If a mutation was successfully introduced into one allele by non-homologous end joining (NHEJ) after CRISPR/Cas9-mediated cleavage, this results in amplification of both wild-type and mutant sequences.
