Horizon Discovery is now offering predesigned synthetic single guide RNA (sgRNA). The sgRNAs are available individually or as library collections, and are being offered as an expansion to the company's Edit-R gene engineering platform. Using synthetic sgRNAs enables researchers to achieve reliable gene knockouts, even in complex, difficult-to-edit cell types and experimental models, Horizon said. The synthetic sgRNAs have been designed to maximize the likelihood of functionally knocking out the gene or genes of interest while minimizing off-target effects.
When paired with Cas9 mRNA or Cas9 protein, the sgRNAs also allow researchers to perform DNA-free gene editing in a new one-part format, streamlining their gene editing workflows without the potential for nuclease or guide integration into the cell's genome. They can also be paired with expressed formats such as Cas9 integrated cell lines.
