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.

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.

Cloning Wizard
Upload your sequence file and DOULIX will guide you through gene assembling process.

Construct design tools
Building constructs and vectors has never been easier. Quickly assemble you DNA parts into constructs using biomodules and then review and edit your sequence usign a powerfull sequence editor.

Constructs collection
Your collection of private and public constructs. Search, share, edit and annotate thousands of constructs using Doulix constrcut designer.

Custom constructs synthesis
Build more, test more and make faster breakthroughs with our custom plasmid assembly service. Skip straight to expression ready, multi-gene plasmids up to 35kbp of greater complexity than ever before.
from 7.5 to 35 kbp
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.

Design a pSEVA vector
Design and validate your SEVA plasmid using hundreds of compatible parts and then seamlessly move to synthesis with DOULIX's algorithm.
max length < 15 kbp
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.

Gibson Wizard
Upload your FASTA file and get dsDNA fragments optimized to run your Gibson assembly in-house.
