In our tests, the Gene Knockout Kit gave us greater than 80 percent knock - out rates for seven targets,» shares Shondra Miller, Ph.D., Director, Center for Advanced Genome Engineering at St. Jude Children's Research Hospital, on Synthego's web site.

The genome - wide analyses showed that Cpf1 was highly specific, showing fewer off - target cleavage sites (6 for LbCpf1 and 12 for AsCpf1), compared to Cas9, cleaving at > 90 sites in the human genome (Fig. 1a).

The team found that such occurrences in the genome are not uncommon; about 50 percent of the analyzed gRNAs had the potential to be affected by variants at their target sites.

When inside the zygotes, the gRNA will seek out its target among the 3 X 109 nt of genetic content in the mouse genome and the Cas9 enzyme will make a cut at the target site.

For editing the genome, this system makes use of 3 components, a guide RNA (gRNA) of about 125 nt that specifies the target, the Cas9 endonuclease that creates the DNA double - strand break (DSB) at the target site, and a donor oligonucleotide or plasmid as the repair material if needed (for knock in models).

Cpf1 also expands the number of sites that can be targeted by CRISPR to AT - rich regions or AT - rich genomes that lack the 3» - NGG PAM sites favored by SpCas9.

After analyzing 964 sites cleaved in vitro by different 11 sgRNAs and measuring indel frequencies at hundreds of off - target sites in cells, we propose an off - target scoring system of each target site for minimizing CRISPR - Cas9 off - target effects in the human genome.

While it's extremely precise, it occasionally modifies DNA at similar sites elsewhere in the genome instead of the target gene.
