Custom constructs synthesis

Plasmid assembly

We are leaders in the production of custom constructs of unprecedented length and complexity. Our plasmid assembly service means you can move from idea to prototype more quickly and with none of the headache of do it yourself assembly.

Assemblies of plasmids from 5 – 35 kbp.
Fully custom assemblies
80% and <20% GC content.
Complexity as standard.
from €0.12 per bp

Our quality promise

All Doulix custom constructs are 100% sequenced verified with Sanger sequencing and produced to our rigorous laboratory procedures according ISO 9001:2008 standards.

100% sanger sequence verified.
ISO 9001:2008 production standards.
Doulix quality promise or your money back.

The extra touch

Industry leading optimisation tools and an expert lab team means we can tackle even the toughest challenges and provide a quality, expression optimised plasmid. Our AI algorithm, trained on thousands of real world experiments computes multiple factors to optimise assembly, and expression.

Troubleshooting as standard.
Scarless assembly.
Expression optimisation.
Design and parts support.

Delivery

Standard turnaround time (TAT) on custom cloning vectors starts from 20 working days days. Of course, depending on complexity TAT may vary accordingly. We estimate delivery during checkout and then keep you up to date in real-time. Meaning you’re ready to start research the moment your samples arrive.

Avg. turnaround 25 working days (may vary)
Real-time project updates and one-to-one support.
Lyophilized DNA options in a range of prep sizes (1 ug, 10 ug, 50 ug, 5 mg)
E. coli stab agar and glycerol stock delivery options.
Add ons available for one stop shopping
Customs and shipping handling included.
