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.

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).

Recommended oligo processing options by application

Choosing the synthesis scale and purification option that is well suited for your application depends on the nature of your downstream applications. We can help you choose the right oligos and purification methods for your application (Table 2).
