Synthesis Principle Of Oligonucleotide

Most oligonucleotides are currently synthesized by solid-phase synthesis, using automated equipment, in which phosphoramidite monomers are required. For example, the phosphoramidite monomer for DNA synthesis mainly consists of bases, deoxyribose, 2-cyanoethyl 5'-DMT and 3'-terminus, and diisopropylamine group, while the phosphoramidite monomer for RNA requires protection of 2'-OH to prevent cross-reaction between 2'-OH and 5'-OH in solid-phase synthesis, and the protecting group is usually TBDMS. Solid-phase synthesis is frequently used nowadays, the traditional solid-phase carriers were controlled microporous glass beads (CPG), but the loading capacity was limited, only 70-80 μmol/g. Nowadays, more high loading capacity solid-phase carriers are used, and the loading capacity is generally up to 250umol/g~350umol/g.

Purification Method Of Oligonucleotide

Oligonucleotides are short-stranded nucleic acids consisting of less than 20 nucleotide units, and purification methods can be selected according to different oligonucleotide lengths, sequences, structures, and purity requirements. The following are some common oligonucleotide purification methods:

Above are some common methods for oligonucleotide purification, Hanbon can offer relevant equipment, which can be used during the RP-HPLC
