HotPlates DNA Oligos are standard, desalted DNA oligos delivered in plates and shipped by our fastest method. If you place your order before the day’s deadline (below), you will receive your plates in 2 business days.

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 electrospray ionization–mass spectrometry methods, and quantified twice by UV spectrophotometry for accurate yield measurements.


  • Normalized to 2 to 10 nmol per well or provided at full synthesis yield
  • 15–60 DNA bases; no modifications or modified bases
  • Deprotected and desalted
  • Each oligo quality controlled by electrospray ionization–mass spectrometry
  • Delivered dry in 96-well plates
  • Minimum of 48 oligos per plate
  • Available in US, Canada, and Europe

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 sysnthesized 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.
