In step 1, Detritylation, the 5'-DMT protecting group is removed from the first, solid-support-linked nucleoside. In step 2, Coupling, the free 5’-OH of the first, solid-support-linked nucleoside attacks the phosphorus of the incoming second nucleoside, displacing its diisopropylamino group. All gene synthesis technologies rely on the chemical synthesis of oligonucleotides to supply the building blocks for enzymatic assembly. The most commonly used method for oligonucleotide synthesis is the cyclical four-step phosphoramidite synthesis method developed in the 1980s (Caruthers et al., 1983, 1987; Fig. 12.1). Oligonucleotide synthesis was performed according to the phosphodiester or phosphotriester approach. Upon completion of the chain assembly, the oligonucleotide was released from the support (19)– (21) by base-induced hydrolysis of the anchoring ester or amide function. The synthesis of DNA or RNA oligonucleotides refers to the chemical synthesis of nucleic acid fragments with defined chemical structures or sequences in various sizes.

For simple oligonucleotides this presents little difficulty, as long as the deprotecting reagents are fresh. However, particular modifications require deprotecting conditions so mild that the bases are not fully deprotected. The global oligonucleotide synthesis market is expected to grow at a CAGR 10.4% from 2019 to 2025 to reach $3.9 billion by 2025. The global oligonucleotide synthesis market is highly competitive and provides robust growth opportunities for biotechnology companies. OligoPilot 400 is used by oligonucleotide pharma and leading suppliers of therapeutic oligonucleotide active pharmaceutical ingredients (APIs) globally.

Automated synthesis is done on solid support, usually controlled pore glass (CPG) or polystyrene. Oligonucleotide synthesis was performed according to the phosphodiester or phosphotriester approach. Upon completion of the chain assembly, the oligonucleotide was released from the support (19)–(21) by base-induced hydrolysis of the anchoring ester or amide function. In Oligonucleotide Synthesis: Methods and Applications, laboratory experts describe in step-by-step detail the powerful new techniques they have developed for oligonucleotide synthesis and for the use of modified oligonucleotides in biotechnology.
