CRISPR Genome Editing in Bacteria

GenScript is pleased to introduce the microbial genome editing service for knock-in, knock-out or gene replacement in bacteria (E. coli). 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.
"GenScript's CRISPR service was a life saver for my research. We were totally stuck on a specific point mutation in our E.coli strain, and GenScript was able to step in and get it done. Updates are provided through every step of the process and they've been a pleasure to deal with."
- Chad Johnston, Ph.D., Banting Postdoctoral Fellow in the Collins Lab at MIT.
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:
- Seamless
- Multigene editing: can knock-out up to 3 genes simultaneously
- Precision down to the base pair
- Easy selection: no selectable marker is required
