Custom Gene Synthesis

BioString Inc. can synthesize genes of any length and complexity to suit your needs. We can synthesize and clone any DNA sequences (even complex, GC-rich, repeated, or long genes) into prokaryotic, eukaryotic or viral vectors. Genes up to 3,000 bp are normally synthesized in 1-2 weeks!

Features & Benefits

  • Free codon optimization upon request.
  • Accept genes over 40-kb in length.
  • Flexible cloning choices: standard cloning, custom cloning and GB Seamless Cloning.
  • Free subcloning into one of our standard vectors.
  • Subcloning into any vector of our choice.

As fast as 5 Business Days, on average 2 weeks turn around time.

100% sequence-guaranteed synthetic genes of the highest quality.

Guarantee: BioString Inc. will guarantee appropriate genes (see Terms & Conditions) to ship from BioString Inc within the above turnaround times once an order has been approved. Appropriate genes that fail to meet the business day turnaround time posted will be credited with half the gene cost on your BioString Inc account (could be used for your further orders).

Terms & Conditions: Our turnaround guarantee is not valid for orders requiring custom cloning, genes with high GC/AT, stretches of homopolymers, low copy vectors, extensive repeats or genes longer than 3kb. Turnaround times can be affected if a gene is toxic to E.coli at propagation. Orders placed before 5:00pm EST (on USA business days) will be considered ordered on the same day.
