Product-specific evaluation notes
Potential advantages
- Reactive handles make the product adaptable across dye-labeling, surface-coupling and ligand-conjugation workflows.
- A defined GalNAc intermediate helps decouple ligand-linker optimization from sequence optimization.
Method limitations
- Functional handles may require orthogonal protection, pH control and rapid purification to avoid hydrolysis, oxidation or cross-reaction.
- In-vitro affinity and in-vivo delivery behavior may diverge; valency, linker length and conjugation site need empirical confirmation.
