Opis

Opis ogólny

DMT-2′O-Methyl-rC(ac) Phosphoramidite is one of the 2′O-Methyl RNA monomers that feature methoxy groups at the 2′-position. Themethoxy groups are perfectly stable in all conditions employed in theassembly of oligonucleotides by automated phosphoramidite synthesis, andin all standard alkaline deprotection conditions.Its key features include:

• High yield of crude oligonucleotides
• Compatible with DNA synthesis
• Can be employed together with DNA or RNA phosphoramidites in thesame synthesis to produce mixmer oligonucleotides
• Recommended deprotection conditions are 8 hours at 55 °C usingconcentrated ammonia solution, or with AMA (concentrated ammonia/40% aqueous methylamine I/I, v/v) for 10 minutes at 65 °C
• Purification and other downstream processing of fully modified 2′OMethyl RNA oligonucleotides are simpler than in the case of RNA, as nospecial precautions are required to provide protection against nucleolyticdegradation
• Synthesis of 2′O-Methyl RNA oligonucleotides is similar to standard DNA synthesis but requires an elongated coupling time (recommended is 6minutes compared to 90 seconds for DNA monomers)
• 2′O-Methyl RNA phosphoramidites are also available with fast deprotection chemistry

Zastosowanie

2′O-Methyl RNA nucleoside including DMT-2′O-Methyl-rC(ac) 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
