The current specification defines the analytical method and acceptance criteria; the released lot result is reported on the CoA.
Additional HPLC, MS or NMR documentation can be agreed during technical review where available.
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.
