Toolbox
From designing an inducible promoter to fabricating an adeno-associated virus for gene knock-down, Doulix offers you a complete set of tools for your synthetic biology application.

Design
All the tools you need for DNA design:
Sequence editor for designing DNA standard parts
Construct Designer to assemble DNA parts into constructs
Start from scratch or choose one of our dedicated tools.

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

Plasmid onboarding
Import your plasmid, vector, phagemid or any circular dsDNA construct into DOULIX and start working right away.

Bulk construct composer
Design hundreds of constructs simultaneously using the Doulix advanced composer. Combine premade and new biomodules to quickly design your constructs.

Biomodule design tools
Biomodules are Doulix design building blocks. Biomodules are linear double-stranded DNA parts. As short as a T7 promoter or as long as an entire metabolic pathway, biomodule are your DNA Lego bricks , you can assemble to build your constructs.

Single sequence
From simple promoters to polycistronic operons, BIOMODULEs are the building blocks of DOULIX. Start designing now!
max length < 25 kbp
Constructs collection
Your collection of private and public constructs. Search, share, edit and annotate thousands of constructs using Doulix constrcut designer.

Cloned fragments synthesis
Save time manual cloning with custom gene cloning of inserts up to 7.5kbp. Pick from a library of application-ready, public backbones, or use your own and store your vectors with us for easy reuse.

Bulk upload
Bulk upload your DNA parts (aka biomodules) as multi- .gb or .fasta file.
