General description

DMT-2′O-Methyl-rA(bz) Phosphoramidite belongs to the class of 2′O-Methyl RNA Phosphoramidites. 2′O-Methyl RNA monomers are compatible with fast deprotection schemes that are based on the application of aliphatic amines, such as methylamine. 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. 2′O-Methyl RNA monomers feature methoxy groups at the 2′-position. The methoxy groups are perfectly stable in all conditions employed in the assembly of oligonucleotides by automated phosphoramidite synthesis, and in all standard alkaline deprotection conditions.

Application

DMT-2′O-Methyl-rA(bz) Phosphoramidite is suitable for use in the preparation of oligonucleotide probes.
