Take control

from Design to Synthesis

Doulix is the only web-based tool
that allows you to move seamlessly
from design to synthesis

With Doulix you can

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.

Bridging the gap between design and synthesis

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.
