mPEG-Hydrazide

mPEGn-Hydrazide is specifically designed for site-specific conjugation with carbonyl groups (e.g., aldehydes and ketones) via hydrazone bond formation, enabling stable PEGylation of glycoproteins, antibodies, and other carbonyl-containing biomolecules. Its key advantages include high selectivity under mild acidic conditions, tunable PEG length (n), and enhanced stability of conjugates, though the hydrazone linkage may exhibit limited stability in highly acidic or alkaline environments.
