The QCgRNA delivery method avoids laborious and time-consuming cloning, screening and sequencing of gRNA plasmid The Clustered Regularly Interspaced Short Palindromic Repeats/CRISPR-associated protein system (CRISPR/Cas) has recently become the most powerful tool available for genome engineering in various organisms. With efficient and proper expression of multiple guide RNAs (gRNAs), the CRISPR/Cas system is particularly suitable for multiplex genome editing. During the past several years, different We have engineered the type II bacterial CRISPR system to function with custom guide RNA (gRNA) in human cells: this involves co- expression of a Cas9 protein bearing a C terminus SV40 nuclear localization signal with one or more guide RNAs (gRNAs) expressed from the human U6 polymerase III promoter. To examine the genome editing capabilities of our system, 293FT cells were co-transfected with the SaCas9 and gRNA viral plasmids. The gRNA plasmids either encoded gRNAs designed to target the human empty spiracles homeobox 1 (EMX) locus (EMX1-sg1 or EMX1-sg2) or did not contain a gRNA (Empty) as a control. CRISPR (/ ˈ k r ɪ s p ər /) (which is an acronym for clustered regularly interspaced short palindromic repeats) is a family of DNA sequences found in the genomes of prokaryotic organisms such as bacteria and archaea.
