GenCRISPR™ SaCas9 2NLS Nuclease

A 20 μl reaction in 1 × SaCas9 Nuclease Reaction Buffer containing linearized plasmid, gRNA, and SaCas9 for 2 hours at 37 °C results in a digestion efficiency of linearized plasmid higher than 90%, as determined by agarose gel electrophoresis.

GenCRISPR™ SaCas9 2NLS Nuclease

GenCRISPR™ SaCas9 2NLS Nuclease is a tag free nuclease produced by expression in an E. coli strain carrying a plasmid encoding the Cas9 gene from Staphylococcus aureus with a nuclear localization signal at both N-terminal and C-terminal.The small size of the nuclease facilitates enhanced in vivo delivery for genome editing in various organisms.

Description

The GenCRISPR™_x000D_ SaCas9 2NLS Nuclease can be formed with the guide RNA into a ribonucleoprotien_x000D_ (RNP) complex. The use of an RNP complex to perform gene editing has been shown_x000D_ to reduce the challenges encountered with other CRISPR gene editing techniques_x000D_ such as viral and plasmid delivery. Challenges include off-target effects, cell_x000D_ viability and transcription/translational challenges. The SaCas9 recognizes an_x000D_ NNGRRT protospacer adjacent motif (PAM) and cleaves target DNA at high_x000D_ efficiency with a variety of guide RNA (gRNA) spacer lengths.
