Metabolic engineering optimizes genetic and regulatory processes in microbes to increase the yield of key compounds, chemicals, and proteins for pharmaceutical and nutraceutical ingredient development. Microorganisms, such as E. coli and S. cerevisiae, are popular cell sources for these molecules, and with the recent CRISPR/Cas9 technology breakthrough, genome editing in bacteria and yeast has become more efficient and precise.
GenScript is pleased to introduce the Microbial genome editing service for knock-in, knock-out or gene replacement in bacteria (E. coli) and yeast (S. cerevisiae). Our service employs a two vector system to target up to three genes simultaneously, ensuring editing accuracy down to the base pair. In addition, to further improve efficacy in bacteria, our scientists have developed a novel λ Red-CRISPR/Cas9 system, which leverages the efficiency of traditional λ Red recombineering with the ease of CRISPR/Cas for seamless, targeted genome editing.
Advantages of GenScript’s CRISPR microbial gene editing system
CRISPR/Cas technology has quickly become one of the easiest and most effective genome editing systems, and when combined with λ Red recombineering has several advantages over the most common editing strategies:
- High efficiency: even in haploid and diploid yeast strains
- Multigene editing: can knock-out up to 3 genes simultaneously
- Precision down to the base pair
- Easy selection: no selectable marker is required
*Standard gene synthesis services (SC1010) can be used for the KI gene insert. Click here to learn more about pricing and turnaround times.
**Pricing does not include the additional cost for gene synthesis, if required.
