Product profile
2'-O-Me-rG(iBu) is classified as base-protected nucleosides (Formula C15H21N5O6; molecular weight 367.36).
2'-O-Me-rG(iBu) supports modified RNA/antisense designs where methylated ribose positions are used to improve stability or reduce unwanted immune stimulation.
For 2'-O-Me-rG(iBu), excessive or poorly positioned substitution can reduce desired enzyme interactions or activity in some assay formats.
