Product profile
2'-O-Me-rC(Ac) is classified as base-protected nucleosides (Formula C12H17N3O6; molecular weight 299.28).
2'-O-Me-rC(Ac) supports modified RNA/antisense designs where methylated ribose positions are used to improve stability or reduce unwanted immune stimulation.
For 2'-O-Me-rC(Ac), excessive or poorly positioned substitution can reduce desired enzyme interactions or activity in some assay formats.
