Compounding this risk, the liver cells that now
contain the DNA for ZFNs will keep making the
nucleases for perhaps years, even though they are no longer needed to guide the new gene to its spot in the genome.
Engineered CRISPR systems for gene editing now
contain two main components, a single guide RNA or sgRNA and Cas - 9
nuclease.
Each assay (15 µL total volue)
contained nuclease free water (5 - 10 µL), cDNA template (2 ng / µL), and gene - specific primers (4.5 pm / µL).
