duplex CRISPR/Cas9 technology
Engineering MethodDuplex CRISPR/Cas9 technology is a genome-editing method that uses two guide RNAs to target intronic sequences flanking an exon, enabling excision of the intervening exon by Cas9-mediated cleavage. In human U-2 OS osteosarcoma cells, it was applied to generate CRY1 knockout, CRY2 knockout, and CRY1/CRY2 double knockout cell models.
