PriorityGENE, TurboGENE, ValueGENE, antibody DNA synthesis, and AAV plasmid synthesis services require you to request a quote before ordering. FragmentGENE, CRISPR construct synthesis, and ssDNA synthesis services are available for direct order, so you do not need to request a quote for these services.
The assembled full-length gene is cloned into the pUC-GW-Kan/Amp vector via the EcoRV site. The final construct is verified with both Sanger DNA sequencing (on at least one strand) and restriction digestion. The sequences of pUC-GW-Kan/Amp can be found here.
Please submit all required starting material to GENEWIZ. For UK projects (40-) samples should be submitted to our UK subsidiary, and for continental Europe projects (50-/90-) samples should be submitted to our German subsidiary (addresses below) as soon as possible after initiating your order (if required). A detailed list of the required starting material is included in section III "How to start your order" of your gene synthesis quotation.
Kindly submit a 5µg aliquot (minimum concentration of 20ng/µL) of the undigested, purified, circular plasmid. Please ensure that the name of the plasmid on the tube matches the name submitted for the order. Include the first page of the order receipt or quote with the submitted plasmid sample to ensure they are accurately identified

The timeline will depend on the size of the gene to be synthesized, the complexity of the vector for cloning, and the requested DNA preparation scale. For reference, the turnaround time for a gene less than 1.5 kb is 8-10 business days with our PriorityGENE service, 7 business days with TurboGENE 7 priority, or 5 business days with TurboGENE 5 priority. A more specific turnaround time for each order is included within the quotation, as well as the “Order Review” page within your online account.
GENEWIZ sample tubes are delivered containing 2-5 µg lyophilized plasmid DNA for gene synthesis orders, or 500 ng - 1 µg purified linear dsDNA for FragmentGENE orders. For resuspension, we recommend the following:
a. Spin the tube briefly to ensure that the contents are on the bottom of the tube
b. Resuspend the sample in a volume appropriate for your needs:
i. For example, 20-50 µL for ~0.25 to ~0.1 µg/µL of sterile high purity water
c. The resuspension solution is dependent on downstream applications - TE may interfere with various enzyme manipulations
d. Vortex briefly, let the DNA tube sit for 2-10 minutes on ice, then vortex again
How do I confirm a gene synthesis quote (PriorityGENE, TurboGENE, ValueGENE, antibody DNA synthesis)?
Our Project Management Team is happy to help with any questions. Please feel free to contact us from 9:00 AM - 6:00 PM CET via phone (+49 (0) 341 520 122-41), email (PM@genewiz.com), or live chat.
Our antibody DNA synthesis service provides synthesis and cloning of your antibody heavy/light chain sequences up to 1.5 kb into any custom vector in as few as 6 business days, the fastest turnaround time on the market. Our PriorityGENE service provides synthesis, assembly, and cloning of sequences with unlimited length on a timely basis.
With our AAV plasmid synthesis service, we can synthesize and clone transgene expression cassettes into custom AAV vectors with high efficiencies. All final products will come bundled with mini-scale or large-scale DNA preparation using our new AAV plasmid preparation protocol and AAV-ITR sequence verified AAV plasmids. This service also offers ITR correction if mutations are found after sequence-verification of these regions.
GENEWIZ can synthesize cloned gene sequences ranging from 1 bp to 50+ kb, using short DNA oligos as building blocks.
GENEWIZ has a proven track record of synthesizing difficult templates, such as GC-rich sequences and sequences with repeats, using our proprietary technologies. With our bioinformatics platform, GENEWIZ optimizes your gene for synthesis.
In some very rare instances, extreme sequence content may be refractory to available sequence verification techniques. GENEWIZ carefully reviews every sequence to estimate difficulty and anticipate project challenges and customizes every project quotation to include an estimated turnaround time and pricing information based on this analysis.
GENEWIZ provides a custom quote for every gene synthesis project. For standard priority, typical gene sequences (non-repetitive, average GC-content) that do not require custom subcloning, no additional fees will apply. For genes with expedited handling, difficult sequences, large inserts, or for projects with custom subcloning requirements, any relevant fees will be indicated in your custom gene synthesis quote.
At GENEWIZ, the protection of our customers' intellectual property is a top priority. Proprietary information is always under client ownership, and GENEWIZ places the utmost importance on confidentiality and privacy. Comprehensive protective measures enable GENEWIZ to earn and maintain the trust and confidence of all customers, collaborators, and partners. For more information about the GENEWIZ Confidentiality Policy, please click here.
GENEWIZ’s codon optimization tool can optimize for multiple critical parameters to stabilize DNA fragments and improve gene expression efficiency. Parameters include, but are not limited to:
a. Codon usage bias
b. GC content
c. mRNA secondary structure
d. Custom desired patterns
e. Custom undesired patterns
f. Repeat sequences (direct repeat, inverted repeat, and dyad repeat)
g. Restriction enzyme recognition sites (deletion or insertion)
Please note, GENEWIZ cannot guarantee final protein expression.
Yes, we offer dual optimization for any two expression systems requested. Additional requirements are also considered for review by the project team. Please note that any dual-system optimization represents a compromise, and a sequence specifically optimized for any given system may outperform the compromise sequence. To add this to your order, please add the request to the “Order Comments” section of your gene synthesis inquiry or email the Project Management Team at PM@genewiz.com.
As the variants are being created from the parent sequence, we can offer a discounted price for variant synthesis. Please keep in mind, variant synthesis does add an additional 3-5 business days to the quoted turnaround time.
CLONING AND MUTAGENESIS
We currently only provide our in-house pUC-GW-Kan/Amp vectors for cloning. If you’d prefer cloning into a different vector, an aliquot of your custom vector will need to be provided upon confirmation of your order.
GENEWIZ can provide transformation and mini-scale plasmid preparation services to create the required template amount for your project. This can be requested as a separate DNA preparation order or can be bundled with your gene synthesis project. If the latter option is suitable, please add an order comment when submitting your gene synthesis inquiry.
GENEWIZ currently only offers cloning vectors based on the pUC-GW-Kan/Amp backbone. We are unable to purchase proprietary vectors on your behalf.
If I cannot provide the starting material at the time of order confirmation, will the gene synthesis steps still be initiated?
Yes, the Project Management Team starts gene synthesis at the time of order confirmation.
We currently offer an in-house recombinational method of cloning that is similar to Gibson assembly. This method can be requested within the order comments of the inquiry form.
Both services offer cloning of an insert from the existing template plasmid into a different destination plasmid. For our subcloning service, the insert to be cloned is already flanked by the restriction sites to be used for cloning. This service is for simple restriction/ligation. The PCR cloning service is offered when there is an additional PCR step required prior to cloning. This could be necessary to add the correct restriction sites, for example. Both options can be requested via the same “Subcloning” form, the Project Management Team will internally determine the best strategy upon receipt of your inquiry.
For any information regarding on-going promotional discounts, please contact your sales representative.

QUALITY AND FINAL DELIVERABLES
Standard deliverables for GENEWIZ gene synthesis projects include:
a. 2-5 µg of lyophilized plasmid containing your desired synthetic construct
b. Certificate of Analysis (COA), including restriction digest
c. Sequence trace data with alignment
d. Sequence of synthetic gene alone and in the designated vector
All reagents, material used, and equipment are kept under strict quality controls by the lab. The Project Management Team may decide to implement additional controls if an uncommon failure rate is observed.
Mutations can be found at multiple stages of a project. For example, a synthesized primer may contain an incorrect base. Mutation correction may delay delivery by 1-4 business days depending on the situation.
The GENEWIZ Project Management Team is happy to address your additional project requests through a new quotation request that references the current open project. Where possible, any discounts applied to the current project will be incorporated into the new quotation. Please note that you must confirm the new project within the ongoing project timeline in order to take advantage of these discounts.
Yes, unless otherwise specified in the quotation due to extreme complexity. Single-strand sequence verification across the entire insert occurs for every synthesis product. If the sequence-verified synthesis product is associated with a large-scale preparation, the product from the large-scale plasmid preparation is sequenced across junctions. Additional sequence verification on the second strand, or after large-scale plasmid preparation, is available if requested (additional charges apply).
Some extremely complex sequences are expected to not be verifiable using current Sanger sequencing techniques and are noted in the quote. In the very rare event where the Project Management Team is not able to deliver the intended material, there will be no charges for your project (unless otherwise specified in the quotation due to extreme complexity).
