CRISPR Cas9 system is recently considered as the most remarkable breakthrough in genome editing technology. Compared with the existing TALEN and ZFN, the CRISPR Cas9 system can provide more precise DNA modification through the RNA-directed Cas9 nucleases. Previous studies have indicated that the on-target gene knockout rate is higher than that of TALEN and ZFN, and the CRISPR Cas9 system is more efficient and economical. CRISPR/Cas9, the most promising gene editing tool, has been widely applied to animal and plant breeding, directed evolution, and the site-specific restoration of genetic diseases.

What are the Advantages of CRISPR-Cas9?

  • Simple Construction: The system based on the Cas9 nuclease and an engineered sgRNA that specifies a target nucleic acid sequences.
  • An Efficient Tool for Genome Editing: The plasmid of sgRNA and Cas9 is easy to construct and utilize.
  • Multiple Functions of CRISPR-Cas9: Gene KO/KI, Genome-scale Screening (sgRNA library), CRISPRi, CRISPRa.
  • Widely applications: The CRISPR-Cas9 system can be applied to different species, including mammals, plants and microorganisms.
