General description
This product is an expression plasmid that utilizes the CMV promoter for strong transient expression of eSpCas9 and GFP linked by a 2A peptide (CMV-eSpCas9-2A-GFP) allowing for easy visualization of successful transfection. The eSpCas9 expression plasmid is one part of a two part CRISPR system with individual eSpCas9 and gRNA expression vectors.

Principle
CRISPR/Cas systems are employed by bacteria and archaea as a defense against invading viruses and plasmids. Recently, the type II CRISPR/Cas system from the bacterium Streptococcus pyogenes has been engineered to function in eukaryotic systems using two molecular components: a single Cas9 protein and a non-coding guide RNA (gRNA). The Cas9 endonuclease can be programmed with a single gRNA, directing a DNA double-strand break (DSB) at a desired genomic location. Similar to DSBs induced by zinc finger nucleases (ZFNs), the cell then activates endogenous DNA repair processes, either non-homologous end joining (NHEJ) or homology-directed repair (HDR), to heal the targeted DSB. Newly engineered eSpCas9 enables the efficient targeted gene editing of established CRISPR systems with the benefit of reduced off-target effects. Point mutations in the chromosome-binding motif of SpCas9, as described by Slaymaker, et al., provide higher on-target fidelity without loss of cleavage efficiency.
