Doulix DNA plasmid visualisation

You do the discovery.
We do the DNA.

Cut development time, multiplex research and accelerate discovery with DNA synthesis you can rely on.

DNA Synthesis you can rely on

Custom DNA synthesis backed by powerful AI for optimisation and manufacture.

dsDNA Fragments

Linear, double stranded DNA fragments up to 2.5 kbp, optimised for assembly and with the lowest error rates in the industry.

Cloned Fragments

Custom fragments up to 7.5kbp, subcloned into the backbone of your choice and optimized for expression and assembly.

Custom Constructs

Large, complex plasmid assemblies up to 35kbp, optimized for expression and with turnaround from 25 days.

Design Less. Build more.

DNA Studio

Simplify your workflows with our free, browser-based bioCAD.

Easily design and validate hundreds of custom constructs with user friendly sequence editors and powerful tools for error correction and optimisation.

And build even more quickly with modular plasmid templates and a library of professional biomodules and constructs.
