Product-specific evaluation notes
Potential advantages
- Base modifications can tune RNA stability, translation behavior, duplex properties or analytical discrimination versus native bases.
- 2′-O-methyl groups are widely used to increase nuclease resistance and modulate hybridization behavior.
Method limitations
- Modification benefits are context-dependent; transcript length, substitution level, enzyme system and analytical purity can change the observed outcome.
- Excessive or poorly positioned substitution can reduce desired enzyme interactions or activity in some assay formats.
