DNA Synthesis services - Doulix Biofoundry
Free your research



Double your output.
Triple the complexity of your design.
Be the first to that breakthrough.
And never touch DNA again…
Welcome to your biofoundry
End to end services for DNA synthesis that free you to pursue more ambitious research.
dsDNA Fragments
Double stranded DNA fragments for performance in a range of applications.
Industry leading fidelity, optimisation as standard and fragments up to 2.5kbp.
Our fragments guarantee greater first time success in cloning and assembly.
from €0.12 /bp
Cloned Fragments
Save tens, hundreds, or even thousands of hours per year manually cloning.
Open a pipeline of custom vectors, with fragment inserts as large as 7.5kbp. Comprehensively optimized for expression and assembly.
from €0.12/bp
Custom Constructs
Build your biggest design yet. Three times faster and for half the cost of in house assembly.
Get fully optimised plasmids up to 35kbp without traditional limits to complexity, in as little as 25 days.
Ideal for long pathway engineering, CRISPR/CAS, artificial chromosomes and where complexity and length are your biggest challenge to success.
from €0.12 /bp



Click & Forget
Double your research output without ever touching a piece of DNA. Simply order, we’ll handle the rest.
With all that time saved, you’re free to pursue your most ambitious designs yet.
Your DNA, on demand.
Securely store your DNA for free with the Doulix Biofoundry to quickly reuse and mutate your constructs.
Enjoy even faster turnaround and pay only for ex novo synthesis.






Powerful AI.
Sophisticated assemblies.
A human touch.
Our DNA synthesis services are built on some pretty advanced tech.
Like the AI we trained to solve synthesis and optimisation problems on thousands of hours of real world, experimental data.
Or our playbook of automated assembly methodologies that build you long, complex constructs quickly and accurately.
But, our real secret is our team; your DNAngels. Always ready to jump two feet into your most ambitious design and say “let’s build that thing.”
World class support when you need it
Throughout your project you get personal, expert support in planning, ordering and troubleshooting your DNA.
We talk strategy, help you discover parts, tackle assembly issues and solve expression hickups.
It’s all part of our obsession with helping you do more with your research.



We respond in hours, not days
>95% project success rates.
Expert support at every step.
Europe’s most pioneering labs trust us with their DNA
