Gene Synthesis

This easy-to-use solution is for researchers who want to skip in-house cloning steps and move quickly into functional studies with 100% sequence-verified clonal DNA.


Enhancement in Progress: We're currently increasing our manufacturing capacity and capabilities which may temporarily impact turn around time (reflected in cart). Click here to reach out to customer care for additional questions.


Complete synthetic genes with 100% sequence verification come in a plasmid cloning vector and are ready to use for a variety of applications.

  • Guaranteed delivery dates
  • Easy online ordering and order tracking
  • No minimum order required, or additional charges for custom vectors


Genes ≤5000 bp will be delivered dry in a circularized plasmid and normalized to 4 µg final yield.* For genes ˃5000 bp, please contact us.


* Gene sequences with added complexity can interfere with assembly and/or sequencing performance. Such sequences may result in less synthesis yield and/or additional services charges.

1 The time required to manufacture a gene is dependent on length, complexity, and vector choice. >85% orders are ready to ship within the number of business days indicated. Sequences that are unstable and/or toxic to E. coli can substantially affect delivery times.

Product details

Genes and MiniGene™ Synthetic Genes are NGS-verified, circular double-stranded DNA in a plasmid. DNA sequences 25 bp to 5 kb are provided with IDT’s in-house cloning vectors, or a custom plasmid vector of your choice (see Table 1) without additional cloning fees. Sequences greater than 5 kb can be reviewed for acceptance as a custom project. Plasmids are delivered dry and ready-to use with an accompanying QC report.

How to order Genes and MiniGenes

Single gene entry

  1. Under Ordering, click Order now.
  2. Enter a name for your gene.
  3. Copy and paste, or enter your desired DNA sequence using A, C, G, and T bases only.
    • Degenerate (mixed bases), or modified bases, are not offered with our synthetic genes products.
    • Test sequence complexity before adding to your order by using the Test Complexity feature—this allows you to make simple changes to the sequence when necessary.
  4. Click Add to Order.
  5. Select a vector from the popup window.
  6. Once you complete the biohazard information, the order will be placed in the shopping cart for checkout.

Multiple gene entry

Under Ordering, click Order now, then select the Bulk Input option at the top left of the ordering tool. Separate your sequences by name as you import a Microsoft Excel spreadsheet or text file.

IDT cloning vectors

All our gene synthesis products are provided in an optimized cloning vector that is ready to be transformed into E. coli. To optimize manufacturing and delivery times, genes ≤5 kb in length are delivered in a “best-fit” vector (Table 1), with a choice between ampicillin or kanamycin selection markers. We also offer vectors that have been optimized for use with Golden Gate Assembly; they will not have the most frequently used Type IIS restriction sites. Upon receiving your gene, you can then subclone it into the vector of your choice using a variety of methods. The identity of the cloning vector used, its sequence and insertion site will be confirmed in the documentation that accompanies your product.

Sequence verification

All inserts for Genes and MiniGene products are sequence-verified by NGS. Upon delivery of the plasmids, a NGS-sequencing report, plasmid map and FASTA file are all available to you in your online IDT account.

Frequently asked questions


Sequence Information is secure and confidential at IDT. Please see our Confidentiality Statement for more information. All online ordering steps, including sequence entry and your choice of parameters, are also secure and protected.

We screen the sequence of every gene, gene fragment, and Megamer™ ssDNA fragment order we receive to (1) identify any regulated and other potentially dangerous pathogen sequences, and (2) verify that IDT’s gene customers are legitimate scientists engaged in beneficial research.

IDT is among the five founding members of the International Gene Synthesis Consortium (IGSC) and helped to create the IGSC’s Harmonized Screening Protocol. The Harmonized Screening Protocol describes the gene sequence and customer screening practices that IGSC member companies employ to prevent the misuse of synthetic genes. IDT takes the steps set out in the Harmonized Screening Protocol to screen the sequences of ordered genes and the prospective customers who submit those orders.

For more information about the IGSC and the Harmonized Screening Protocol, please visit the website at


In October 2010, the United States government issued final Screening Framework Guidance for Providers of Synthetic Double-Stranded DNA, describing how commercial providers of synthetic genes should perform gene sequence and customer screening. IDT and the other IGSC member companies supported the adoption of the Screening Framework Guidance, and IDT follows that Guidance in its application of the Harmonized Screening Protocol.
