I. [Product Introduction]
Mal-PEG-Lysines (Maleimide-Polyethylene Glycol-Lysine) is an organic intermediate modified with bifunctional reactive groups. Its maleimide group can specifically bind to sulfhydryl groups, and the lysine backbone provides an amino coupling site, which is widely used in biological coupling reaction systems. This compound has important application value in the synthesis of pharmaceutical intermediates, the construction of nanocarriers, and enzyme-catalyzed reactions due to the excellent water solubility and biocompatibility of the PEG segment.
