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, and quantitated twice by UV spectrophotometry for accurate yield measurements.

For oligos ≥20 bases, we offer the following yield guarantees:

ProductAvailable lengthGuaranteed yield
25 nmol DNA oligo15–60 bases3 ODs
100 nmol DNA oligo10–90 bases6 ODs
250 nmol DNA oligo5–100 bases15 ODs

5 µmol DNA oligo5–100 bases250 ODs
10 µmol DNA oligo5–100 bases500 ODs

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.

Figure 1. Proportion of full-length product is a factor of coupling efficiency. DNA oligos from IDT are synthesized on proprietary platforms that deliver higher coupling efficiency than industry standards. The increasing importance of coupling efficiency to increased oligo length is shown.

Figure 2. Daily monitoring of coupling efficiency at all IDT manufacturing sites. Many variables can lead to reduced oligo quality, including ambient temperature, humidity, and input reagents). 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.
