Oligonucleotides are the starting point for many of today’s biology research, drug discovery, and diagnostics applications. These highly technical applications demand high-quality oligonucleotides for success. Our oligos are made to your specifications with rigorous quality control and quick turnaround for use in a variety of applications, including PCR, cloning, sequencing, and gene detection.

All oligos are manufactured using controlled procedures certified against ISO 9001:2015 and ISO 13485:2016 standards.
Our custom DNA Oligos shipments from Scotland, UK to EU member state countries are expected to be delivered within 2 – 3 days of the ship date from our manufacturing and shipping site. Such shipments are subject to customs clearance into the EU and this is an external factor which we have limited control over.
Please be assured that we are monitoring such shipments on a weekly basis in collaboration with our carrier partner.

Our custom oligonucleotide synthesis process
Our custom DNA oligos are synthesized on a highly automated, computer-controlled system using standard cyano-ethyl phosphoramidite chemistry. Post-synthesis QC employs electrospray ionization mass spectrometry (ESI MS) for all oligos. As a standard practice, 100% of synthesized oligos are measured for quality control whether provided in tubes or in plates.

Choose DNA oligos for your application
Which kind of oligos are right for me?
While our value oligo format represents our most economical and fastest way to order (25 or 50 nmol in tube formats with a range of purification options to suit your applications), if your research demands a scale larger than 50 nmol, a different format, or requires 5′, 3′, or internal modifications, then our standard DNA oligo formats have you covered (Table 1).
Table 1. Which kind of oligos are right for me?
| Value oligos | Standard oligos |
|---|---|
| Price is calculated per oligo | Price is calculated per base |
|
|
| Not available with modifications | 5′, internal, and 3′ modifications are available |
