DNA/RNA Synthesis Reagents

DNA/RNA Synthesis Reagents

Synthetic DNA/RNA are important research tools in therapeutic DNA/RNA area.

There are four major chemical synthetic methods of DNA/RNA:

  1. Contemporary H-phosphonate method
  2. Phosphodiester method
  3. Phosphotriester method
  4. Phophitetriester method

In which, phosphitetriester method is commonly used for DNA/RNA solid-phase synthesis nowadays.

In phosphitetriester method, DNA/RNA chemical synthesis is carried out by a stepwise addition, the synthesis process contains four chemical reactions:

  • Step 1: De-blocking
  • Step 2: Coupling
  • Step 3: Oxidation
  • Step 4: Capping

Oligonucleotide  synthesis from phosphoramidites. Figure 1. Oligonucleotide synthesis from phosphoramidites.

As DNA/RNA contain at least one -OH group, the introduction of the suitable protecting groups enables the oligo to convert to the respective phosphoramidite, and then it can couple the latter. Therefore, phosphoramidite coupling reaction makes phophoramidites the most important building blocks in DNA/RNA synthesis.

We can provide a variety of phosphoramidites for common RNA synthesis and sensitive DNA/RNA synthesis.
