Targeted Cloning of Large Pathways
DNAtrap™ technology provides custom cloning of biosynthetic gene clusters and long operons up to 150 kb in length.DNAtrap™️
Biosynthetic Gene Cluster Cloning Service
DNAtrap™ technology provides custom cloning of biosynthetic gene clusters (BGCs) up to 150 kb in length. Varigen’s CRISPR/Cas9-based technology is significantly faster than competing techniques as we can deliver intact gene cluster clones from your sequenced microbe in 10 days. We have recently broadened our technology to include custom cloning from both fungal and bacterial targets.
DNAtrap™
Recombinant BGCs in 10 days!
Varigen has extensive experience cloning large, difficult DNA fragments, such as polyketide synthase (PKS), non-ribosomal peptide synthase (NRPS), and hybrid BGCs, as well as difficult to PCR fragments like virulence factor pathways. In these examples, unique restriction digest fragment patterns match the in silico simulated digest pattern, demonstrating the entire genomic fragment was correctly cloned into the BAC plasmid vector.
Testimonials
We have had 100% success using Varigen’s technology platform to clone specific DNA fragments up to 40kb into our destination vector. The insert DNA fragments were precision-excised from fungal genomic DNA using Varigen’s CRISPR/Cas9 technology. Importantly, our fungal strains are diverse wild-type isolates, not conditioned laboratory strains. Varigen’s capabilities and technology have exceeded our most ambitious expectations.
I had worked on cloning a pathway by conventional methods for over three months with little success. Varigen was able to perform the targeted cloning of an entire bacterial secretion pathway in less than 10 days! The amount of time, money, and frustration that your service saved our lab cannot be overstated. I look forward to doing business with you again.
