CRISPR has rapidly become the genome editing tool of choice in many eukaryote organisms, however its use in bacteria has been limited until recently. Many bacteria do not possess robust DNA repair systems as eukaryotes do, and therefore CRISPR-induced double-stranded DNA breaks are lethal. To improve recombination rates scientists have employed phage-derived (Lambda Red) recombinases to carry out enhanced homologous recombination – referred to as recombineering. When Lambda Red recombination is coupled with CRISPR it provides a powerful tool for selecting against non-edited cells, allowing for highly precise and efficient scarless genome editing.
Bacteria possess great potential to produce complex molecules with applications in therapeutics, agriculture, and industry. E. coli has long been a preferred choice for metabolic engineering and the production of such molecules due to its well-characterization and abundance of available genetic tools. Our custom bacterial gene knockout and knock-in services offer highly specific and efficient editing of the E. coli genome.
When the locus of your knock-in isn’t a concern, consider our E. coli Safe Harbor Gene Knock-In Service. Our expert scientists have verified this “safe harbor” or “hotspot” locus in the E. coli genome for safe guarded genomic expression. Use this service for reliable expression of your gene of interest. To order bacterial genome editing services, simply send us the information on your desired gene knock-in/knockout and E. coli strain, and we’ll do the rest!
