GenCRISPR™ Cas9 v1.2是一种无标签的核酸酶，通过在携带编码来自链球菌属（Streptococcus pyogenes）Cas9基因的质粒的大肠杆菌菌株中表达而产生。

GenCRISPR™ Cas9 v1.2 is a tag free nuclease produced by expression in an E. coli strain carrying a plasmid encoding the Cas9 gene from Streptococcus pyogenes with a biparticle nucleus localization signal (BPNLS) at N-terminal and a nucleoplasmin nucleus localization signal (nucleoplasmin NLS) at C-terminal. It has been reported that BPNLS and nucleoplasmin NLS are able to improve the gene editing efficiency.

Description

The GenCRISPR™ Cas9 v1.2 can be formed with the guide RNA into a ribonucleoprotien (RNP) complex. The use of an RNP complex to perform gene editing has been shown to reduce the challenges encountered with other CRISPR gene editing techniques such as viral and plasmid delivery. Challenges include off-target effects, cell viability and transcription/translational challenges.GenCRISPR™ Cas9 v1.2 is a tag free nuclease produced by expression in an E. coli strain carrying a plasmid encoding the Cas9 gene from Streptococcus pyogenes with a biparticle nucleus localization signal (BPNLS) at N-terminal and a nucleoplasmin nucleus localization signal (nucleoplasmin NLS) at C-terminal.
