Methods for large Scale DNA Oligonucleotide Synthesis

Different large-scale DNA oligonucleotide synthesis methods have different advantages and impacts on downstream gene synthesis processes. BOC Sciences can select the most appropriate large-scale DNA oligonucleotide synthesis method for the customer's application to accelerate the project while reducing costs and ensuring quality.

Column-based DNA Oligonucleotide Synthesis

Solid-phase phosphoramidite chemistry is the most prevalent method of large-scale DNA oligonucleotide synthesis and, as shown in the figure below, consists of a four-step cycle in which a base is added one at a time to a growing strand of oligonucleotides attached to a solid support. The method typically synthesizes 96-384 oligonucleotides simultaneously on a scale of 10 to 100 nmol. Improvements in raw materials, automation, processing, and purification methods have led to routine syntheses up to∼100 nt. The cost per nucleotide for this method is much lower but the error rate is 1/200 or higher. The major errors in the oligonucleotides obtained by purification centered on single-base deletions, which were mainly due to failure to remove DMT or inefficiencies in the coupling and capping steps.

Array-based DNA Oligonucleotide Synthesis

Photo-activated chemistry for spatially localized polymer synthesis on surfaces has paved the way for the development of DNA microarrays. Standard mask-based lithography can be used to selectively deprotect photo-unstable nucleoside phosphoramidites. Inkjet-based nucleotide printing on the array surface allows oligonucleotide synthesis using standard phosphoramidite chemicals. Oligonucleotides produced by microarrays are 2-4 orders of magnitude cheaper than column-based oligonucleotides, depending on length, size, and platform.
