Customised DNA oligos according to your specifications
Select from the huge variety of modifications, purification options and synthesis scales
Eurofins Genomics is one of the biggest users of oligos itself . We take this advantage and closely cooperate with our colleagues performing Sanger sequencing, Next Gen Sequencing, cloning, gene synthesis and qPCR services for optimised specifications and performance of primers and probes.
You can rely on our expertise when you choose our validated Optimised Application Oligos.
If you prefer to select your own parameters, choose our Custom DNA Oligos:
- Huge variety of DNA modifications
- Different oligo purification options
- Synthesis scales from 0.01 µmol up to 10 µmol
- Delivery format lyophilised or concentration adjusted
- Aliquoting & plate copies available
- Quality ensured by OD measurement and MALDI-TOF MS
To ensure highest quality and fast turnaround times, our Custom DNA Oligos are
- Synthesised in a high throughput production facility
- Processed using highly automated technologies
- Monitored by a sophisticated barcode driven production system
- Finally checked by MALDI-TOF MS analysis
We also offer double strand DNA in any length and highest quality with our gene synthesis service.
