Product-specific evaluation notes
Potential advantages
- A defined GalNAc intermediate helps decouple ligand-linker optimization from sequence optimization.
Method limitations
- In-vitro affinity and in-vivo delivery behavior may diverge; valency, linker length and conjugation site need empirical confirmation.
