Tools for flexible protocols, and fast, high-quality results

  • Speed—clone up to 10 DNA fragments simultaneously; assemble existing fragments without restriction digest or PCR amplification
  • Precision—no extra sequences; clone what you want where you want
  • Flexibility—use our linearized vectors or any vector of your choice
  • Simplicityfree online tool  guides you through planning, design and assembly of your construct and PCR primer design, if needed

Expert Vector Construction: The GeneArt® Seamless Cloning and Assembly Kit eliminates multiple rounds of restriction enzyme analysis and digestion, DNA end-repair, de-phosphorylation, ligation, enzyme inactivation and clean-up, and loss of precious DNA. It’s what our experts use to make vectors, and they save 3-4 weeks versus traditional RE cloning methods.
