I. [Product Description]
Mal-PEG-ASP (Maleimide-Polyethylene Glycol-Aspartic Acid) is a multifunctional organic intermediate that enables efficient coupling reactions through precise molecular design. It is widely used in the preparation of biocompatible materials. Its maleimide group can specifically bind to thiol groups, the polyethylene glycol chain enhances water solubility, and the aspartic acid residue provides functional modification sites. It is suitable for the preparation of catalyst carriers and the directional coupling of biomolecules.
