Description

General Description

Alkyne-Poly(L-Lysine) is a functional cationic polypeptide designed for bioorthogonal conjugation and advanced drug delivery applications. The terminal alkyne group readily participates in copper-catalyzed azide-alkyne cycloaddition (CuAAC) with azide-containing molecules, forming stable triazole linkages with excellent efficiency and selectivity.

The poly(L-lysine) backbone contains numerous primary amine groups that readily complex with negatively charged nucleic acids such as DNA, RNA, siRNA, and mRNA. These amine groups also react with NHS esters, activated carboxylic acids, aldehydes, epoxides, and other amine-reactive molecules, providing versatile opportunities for further functionalization.

The combination of a cationic biodegradable polypeptide and a terminal alkyne functionality makes Alkyne-PLL an excellent material for gene delivery, polymer-drug conjugates, click chemistry, nanoparticle functionalization, hydrogel preparation, molecular imaging, and advanced biomaterials research.
