A 20 μl reaction in 1 × Cas9 Nuclease Reaction Buffer containing linearized plasmid, gRNA, and Cas9 for 1 hour at 37 °C results in a digestion efficiency of linearized plasmid higher than 90%, as determined by agarose gel electrophoresis.

Human Jurkat cells were cultured for the test. The cells were transfected with GenCRISPR™ Cas9 v1.2 (Z03702)+ sgRNA (synthesized from GenScript gene@genscript.com) for human TCRαβ gene knock out by electroporation. After transfection and cell culture, measure the gene editing efficiency. GenCRISPR™ Cas9 v1.2 shows a much high editing efficiency.

Human T cells were cultured for the test. The cells were transfected with GenCRISPR™ Cas9 v1.2 (Z03702)+ sgRNA (synthesized from GenScript gene@genscript.com) + dsDNA template (synthesized from GenScript gene@genscript.com) for knock in test at TCRαβ site by electroporation. After transfection and cell culture, measure the editing efficiency.

GenCRISPR™ Cas9 v1.2

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.
