Gene Excision by Dual-Guide CRISPR-Cas9.
Methods in molecular biology (Clifton, N.J.), 2307: 85-94 PMID 33847983 DOI 10.1007/978-1-0716-1414-3_5
Abstract
CRISPR-Cas9 is frequently used for creating double-strand DNA breaks that result in indels through non-homologous end joining. Indels can revert to wild-type sequence and require sequencing or complex assays to measure. Cutting by two guide RNAs can lead to single indels at either cut site or simultaneous cutting at both sites and repair leading to gene excision.
