Synthetic Biology
from Design to Synthesis
Doulix is the only DNA design software that integrates DNA synthesis out of the box


















The synthetic biology full-stack




A DNA Editor like no others
Don’t compromise and enjoy the only DNA editor that combines the best of both worlds: the ease of use of pre-made biomodules with power of a full-fledged sequence editor. In addition, you can harness the power of AI to automatically compute the optimal fragments for the assembly method of your choice including: GoldenGate, Gibson, In-Fusion, SureVector and DNAmate.
Your personal DNA foundry
Whether you need a 30 kbp cosmid or few kbp dsDNA fragments to run your assembly in house, Doulix provides you with uncompromised DNA quality (error rate < 10-4) and unmatched turn-around time (starting from as little as 6 working days). You can also choose from a broad range of complementary services such as DNA prep, endotoxin removal, AAV packaging. Your personal DNA foundry is open 24/7.

Our Benefits



Reduce Mistakes
No more missing bp or frame-shifts as you copy and paste your sequences between your editor and your gene synthesis provider.




Boost Results
Simply import your sequence (.txt, .gb, and .fasta) with our user-friendly UI. And then edit and annotate it in real-time before synthesis.





Save Time
No more wasting time waiting for pending orders to be confirmed. Check your sequence for manufacturability as you type.




Save Money
No more duplicate orders or last-minute surprises, get all-included quotes and re-use archived fragments and constructs.

Details Make The Difference




Free Subcloning
Free subcloning into the most common standard vectors, including pSEVA_181, CIDAR DVA, pDLX_1A100 and pSB1C3.




Custom Vectors
Save time on subcloning and colony screening. Get your DNA strings subcloned directly into your vector of choice for as little as 39.99 euros.





Delivery options
As little as 100ng as much as 1mg, you can choose among different scale options and have your sample delivered as lyophilized, stab agar or glycerol stock.




Purity options
From research-grade to endotoxin-free, you can choose the purity grade that meets your needs. For more demanding applications, LAL test available on request.




ISO 9001 certified




Doulix API
Forget copy-paste mistakes, no more uploads. With our API portfolio, you can connect your LIMS systems directly to Doulix backend and execute quoting, ordering, and sequence analysis.




Vector vault
Store your constructs for later use or share them with your community. Doulix offers a broad range of options for sample storage in EU.




Made in Europe
Oligo assembly, error-correction, and quality controls are rigorously carried out in house at our facility in Mestre, Italy. To arrange a visit to our labs, mail to info at doulix dot com

Let's meet!
Designed around you
for RESEARCHERS
No more missing bp or frame-shifts as you copy and paste your sequences, Doulix brings together design and synthesis
for iGEMers
We worked with iGEM teams to craft an all-in-one solution tailored for you, including: iGEM sequence database, kits, synthesis and subcloning bundle.
for PIs and Groups
Save time by sharing resources with your team and enable different types of access for data, assigning budgets and track expenses for different projects.
Empowering synthetic biology
Biology is going through a radical paradigm shift over the last decade evolving from a qualitative/descriptive science to quantitative/engineering one. With DOULIX you can design custom construct with confidence choosing among hundreds of lab-tested biomodules and avoid most common design flaws using the validation wizard.
