Description

Description générale

DMT-2′O-Methyl-rA(bz) Phosphoramidite is a 2′O-Methyl RNA monomer that is compatible with fast deprotection schemes that are based on the application of aliphatic amines, such as methylamine. Modern phosphoramidite-mediated synthesis has enabled routine high-yielding preparations of 2′O-Methyl RNA oligonucleotides. High-quality RNA phosphoramidites are key to low failure rates, the high biological activity of synthesis products, and cost-effectiveness. 2′O-Methyl RNA is a nucleic acid analog that is characterized by the exceptional hybridization properties that it imparts with complementary DNA or RNA, as well as increased stability against enzymatic degradation compared to natural nucleic acids.

Application

2′O-Methyl RNA nucleoside including DMT-2′O-Methyl-rA(bz) Phosphoramidite can be advantageously incorporated in nucleic acid probes with RNA or DNA for in-vivo or in-vitro applications to convey nuclease resistance.The unique combination of properties of 2′O-Methyl RNA had found widespread use in the fields of:

• Diagnostic probes
• Aptamer and ribozyme development
• Mixed 2′O-Methyl-RNA/DNA antisense molecules (a)
