I. [Product Description]
Mal-PEG-Tryptophan is a high-purity organic intermediate precisely coupled by maleimide groups, polyethylene glycol (PEG) chains, and tryptophan residues. It combines the hydrophilicity and biocompatibility of PEG and can be used as an efficient catalyst or pharmaceutical intermediate in bioconjugation reactions. Its maleimide group can specifically bind to thiol groups, making it suitable for the directional modification of complex molecular systems.
