Figure 1: Cloning 2 DNA fragments in the pYES1L vector. In the first two examples (Figure 1), the cloning efficiencies for two different oligonucleotide stitching experiments are shown using pYES1L as the vector. The procedure can also be used to introduce deletions, insertions, or other desired modifications to the final assembled recombinant DNA molecule. |
GeneArt® High-Order and Genetic Assembly relies on yeast’s ability to take up and recombine DNA fragments with high efficiency. This process, termed transformation-associated recombination, greatly reduces handling of DNA and eliminates restriction endonuclease digestion and ligation while allowing precise assembly of DNA fragments.
GeneArt® Seamless Cloning and Assembly Kits work great together with GeneArt® Strings™ DNA Fragments. This new service offers custom-made DNA fragments up to 1,000 bp ready for cloning and assembly and delivered in only 5-7 business days.
Figure 2 The system is used to assemble three DNA fragments, one of which has end-terminal homology with the linear cloning vector. The remaining fragments are assembled using stitching oligonucleotides. |
After verifying “positive” colonies containing the final assembled construct, the construct is transferred into E. coli for large scale plasmid preps for downstream applications. |
Figure 3: Cloning efficiency for different numbers of 10 kbp fragments amplified by PCR. Figure 3 illustrates the high cloning efficiency for 1, 3 and 10 DNA fragments of 10 kbp each, amplified by Platinum® PCR SuperMix High Fidelity and cloned into pYES1L. Constructs were transferred to E.coli and the DNA junctions were sequenced for accuracy. |
Figure 4: Comparison of the cloning efficiencies of the GeneArt® Seamless Cloning and Assembly Kit with the GeneArt® High-Order Genetic Assembly System. A cloning efficiency of over 90% was observed when assembling 10 fragments of 5 kb each in pYES1L. The fragments were amplified with Platinum® PCR SuperMix High Fidelity and assembled into pYES1L using the GeneArt® High-Order Genetic Assembly System the cloning efficiency is over 90%. |
The DNA Oligo Designer is an intuitive, web-based tool to guide you when you are designing your desired DNA molecule. The tool minimizes planning time, identifies potential pitfalls, and performs in silico cloning. The DNA Oligo Designer also provides a graphic representation of the final assembled molecule as well as a downloadable GenBank file compatible with Vector NTI Advance® and other software for molecular biology workflows.
The DNA Oligo Designer also sends your required DNA oligonucleotides directly to your shopping cart for easy ordering in countries where this functionality is available.
