DNA Oligonucleotides are short, single- and double-stranded synthetic DNA sequences that can be used in a variety of molecular biology applications. 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-MS
* With the exception of mixed base oligos, which could potentially represent multiple sequences and therefore cannot be evaluated by ESI -MS.
For standard, desalted oligos ≥20 bases, we offer the following yield guarantees:
|Product||Available length||Guaranteed yield*|
|25 nmole DNA Oligo||15–60 bases||10 nmol|
|100 nmole DNA Oligo||10–90 bases||30 nmol|
|250 nmole DNA Oligo||5–100 bases||50 nmol|
|1 µmole DNA Oligo||5–100 bases||200 nmol|
|2 µmole DNA Oligo||5–100 bases||400 nmol|
5 µmole DNA Oligo
|5–100 bases||1000 nmol|
|10 µmole 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 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 fast turnaround times. Our ability to control these variables allows us to consistently produce high-quality oligos for use in routine and specialized applications.
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 result in 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 a reliable product that helps provide confidence in your research.
Figure 1. IDT proprietary platforms have a better coupling efficiency than other suppliers, which provides more full-length oligonucleotides in your order. Small increases in coupling efficiency (≤1%) result in measurable increases in full-length product yield. The curves represent the theoretical yield for different lengths of oligos based on a coupling efficiency of 99.4% (IDT Oligos, n = 126) and 99.1% (other suppliers, n = 134 from three different suppliers) using the formula: percent full length product = (eff )(n-1)*100 where eff = coupling efficiency (for example, 99.4% = 0.994) and (n–1) is the number of coupling reactions needed to make an oligo of length n.
Figure 2. IDT tracks coupling efficiency at our manufacturing sites to ensure consistent quality. Many variables can lead to reduced oligo quality, including ambient temperature, humidity, and input reagents. Monitoring of coupling efficiency at IDT manufacturing sites ensures that we provide our customers with high-quality products. A quarterly average is shown (n = 16 per manufacturing site).

Calculating this conversion requires you to know the extinction coefficient for your sequence. With this, you can easily convert from your nanomole amount to ODs. To determine the extinction coefficient, you can analyze your sequence using IDT's free OligoAnalyzer™ tool. Results from this analysis will also provide you with nmol/OD260 and µg/OD260 values.
