I. [Product Description] 
Casein-PEG-Aminooxy (Casein-Polyethylene Glycol-Aminooxy) is a multifunctional organic intermediate with high-efficiency biological coupling ability. Through the stability of casein and the steric hindrance effect of the PEG chain, it significantly enhances the water solubility and directional modification efficiency of target molecules. This compound can be used as a biocompatible cross-linking agent or surface functionalization reagent, and is widely used in the field of polymer material modification and functionalization development.
