In this study, we demonstrated that another type of Type II CRISPR-Cas system—the II type Cas9 system—also possesses “trans-cleavage” activity. This activity is guided by crRNA and tracrRNA and is activated via the binding of DNA or RNA targets. By combining the trans-cleavage activity of the Cas9 effector nuclease with nucleic acid amplification t...

Transcriptomics Technology Tracking-Seq Reveals Off-Target Effect Heterogeneity Mediated by CRISPR-Cas9 Research Background With the rapid development of genome editing technologies, the CRISPR-Cas9 system has been widely used in biomedical research due to its high efficiency and ease of operation. However, a significant issue with the CRISPR-Cas9 ...
