SDP

3'-TBDMS-Bz-rA Phosphoramidite is a phosphoramidite monomer used in the synthesis of oligonucleotides. Oligonucleotides are short-chain nucleic acids, composed of deoxyribonucleotides or ribonucleotides, that can specifically "silence" genes by complementary base pairing with DNA, mRNA, or pre-mRNA, thereby inhibiting protein expression.

  • Used in the synthesis of oligonucleotides.
  • Enables specific gene silencing through complementary base pairing.
  • Inhibits the expression of numerous proteins.
