Rapid HPLC™ DNA Oligos

HPLC purified oligos offer speed without comprising the quality of your oligos. Each Rapid HPLC DNA Oligo is quality controlled by electrospray ionization mass spectrometry and capillary electrophoresis or analytical HPLC/UPLC.


Rapid HPLC Oligos

Delivered dry in tubes. To meet the ordering deadline, orders for Rapid HPLC Oligos must be placed online.


The Rapid HPLC fee for expedited HPLC purification will be applied for each oligo.

Product Details

HPLC purification

High performance liquid chromatography (HPLC) purification, a form of column chromatography, can be performed in one of two ways. Reverse-phase (RP) HPLC separates oligos based on their affinity for particular solvents, while ion-exchange (IE) HPLC separates oligonucleotides based on their charge. The type of HPLC we use is dependent on the sequence and molecular characteristics of the oligo. HPLC-purified oligos experience an unavoidable loss of mass, but this is offset by the dramatic increase in purity. To learn more about our purification services, click here.

Rapid HPLC Oligos are purified using the same equipment and protocols as standard HPLC purification. All oligos are quality control checked by electrospray ionization­ mass spectrometry (ESI-MS), with traces available for free on our website. If you place your order before the day's deadline (below), your Rapid HPLC Oligos will be shipped on the next business day.

Product Data

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 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 commitment to quality and consistency results in a reliable product that helps provide confidence in your research. An important measure of quality for any oligo manufacturer is coupling efficiency, as this directly affects the amount of full-length product you receive. Our manufacturing methods allow us to achieve high coupling efficiencies (Figure 1).

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 following 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.
