Product-specific evaluation notes
Potential advantages
- Reactive handles make the product adaptable across dye-labeling, surface-coupling and ligand-conjugation workflows.
- Dideoxy analogs provide clear extension-stop behavior when accepted by a polymerase.
- 2′-O-MOE motifs are often selected for enhanced nuclease resistance and improved duplex stability.
Method limitations
- Functional handles may require orthogonal protection, pH control and rapid purification to avoid hydrolysis, oxidation or cross-reaction.
- Polymerase acceptance varies; absence of a 3′-OH prevents further extension after incorporation.
- MOE placement needs design control, especially when RNase H recruitment or steric profile matters.
