Cloning is commonly used to amplify DNA fragments containing whole genes, but it can also be used to amplify any DNA sequence such as promoters, non-coding sequences and randomly fragmented DNA.

It is used in a wide array of biological experiments and practical applications ranging from genetic fingerprinting to large scale protein production.

We offer clones ready to use and a wide variety of cloning systems, including novel transcription-free cloning vectors, that improve cloning yields, reduce cloning bias, and improve sequencing throughput.

Choose from our genome-wide collection of the ready-to-use clones or let us make your customized clones by gene synthesis.

  • Comprehensive
  • Expression-ready
  • Transfection-grade
  • Flexible Shuttling

IDT and SGI-DNA have partnered to offer custom gene synthesis. Synthetic gene products manufactured by IDT and SGI-DNA can be ordered through the IDT website, allowing researchers to save money spent on construction and cloning, and saving significant time and effort by outsourcing the production of hard-to-clone sequences that often result in repeated failures.

All genes are constructed using the highest quality oligonucleotides from IDT. Genes arrive in a plasmid cloning vector and are ready for use in a variety of applications.

Gene sequences with added complexity (such as homopolymeric runs, critical hairpin structures or G/C content), which can interfere with assembly and/or sequencing performance may result in extra service charges. For more information about potential types of complexity, please see the Overview tab.
