Generate consistently reliable data from the highest fidelity oligos available
All single-stranded and duplexed DNA sequences are produced with industry-leading coupling efficiencies, resulting in higher quality DNA products. Our specialized platforms allow us to deliver the purest primers for PCR,
* With the exception of mixed base oligos, which could potentially represent multiple sequences and therefore cannot be accurately evaluated by ESI mass spectrometry.

DNA oligos are short, single- and double-stranded synthetic DNA sequences that can be used in nearly any molecular biology application. Using the Oligo Entry ordering tool, you can design your oligos to contain any DNA sequence you require and select from hundreds of modifications to suit your specific research needs.
Every DNA oligo you receive will be deprotected and desalted to remove small molecule impurities. In addition, your oligos will be quality controlled via proprietary ESI-mass spectrometry methods
* With the exception of mixed base oligos, which could potentially represent multiple sequences and therefore cannot be accurately evaluated by ESI mass spectrometry.
For standard, desalted oligos ≥20 bases, we offer the following yield guarantees:
Product | Available length | Guaranteed yield* |
---|---|---|
25 nmol DNA oligo | 15–60 bases | 10 nmol |
100 nmol DNA oligo | 10–90 bases | 30 nmol |
250 nmol DNA oligo | 5–100 bases | 50 nmol |
1 µmol DNA oligo | 5–100 bases | 200 nmol |
2 µmol DNA oligo | 5–100 bases | 400 nmol |
5 µmol DNA oligo | 5–100 bases | 1000 nmol |
10 µmol DNA oligo | 5–100 bases | 2000 nmol |
* Guaranteed yield for unmodified oligos 25–50 bases; will vary with oligo composition, length, and purification.
IDT’s long-standing reputation as a leader and pioneer in custom oligo manufacturing is largely due to our vertically integrated proprietary synthesis platforms. Nearly every component of our manufacturing process is designed and developed in-house, including specialized synthesizers that can accommodate the most demanding oligo requests, and high-throughput automation systems that ensure the fastest turnaround times possible. We do not rely on third-party manufacturers for any of the machines or chemical reagents used for synthesis, allowing us to easily monitor and refine instruments and reagents with ease. Our ability to control these variables allows us to produce oligos that are unmatched in quality and consistency.
An important measure of quality for any oligo manufacturer is coupling efficiency, because this directly affects the amount of full-length product you receive. Our manufacturing processes achieve extremely high coupling efficiencies (Figure 1) and are standardized across our global manufacturing sites (Figure 2) to provide you with most consistent quality in the industry. No matter where in the world you are conducting your research, an IDT oligo is an IDT oligo. Our commitment to quality and consistency results in an extremely reliable product that will perform the same each time it is used. Because your research requires a steady supply of oligos over time, this reliability provides confidence in your research.

We track coupling efficiency at all of our manufacturing sites to ensure consistent quality with change in variables. A 30-day rolling average is shown.
