DBCO-PEG 5-NHS酯与伯胺(例如，赖氨酸残基的侧链或氨基硅烷包被的表面)在pH 7-9下形成共价键。亲水性聚乙二醇(PEG)间隔臂赋予水溶性，其被转移到标记分子，从而减少储存在溶液中的标记蛋白质的聚集。PEG间隔臂提供长且柔性的连接，其最小化与互补的含叠氮化物分子的连接有关的空间位阻。

DBCO-PEG5-NHS Ester reacts specifically and efficiently with a primary amine (e.g., side chain of lysine residues or aminosilane-coated surfaces) at pH 7-9 to form a covalent bond. The hydrophilic polyethylene glycol (PEG) spacer arm imparts water solubility that is transferred to the labeled molecule, thus reducing aggregation of labeled proteins stored in solution. The PEG spacer arm provides a long and flexible connection that minimizes steric hindrance involved with ligation to complementary azide-containing molecules.DBCO reagents are the most commonly used substrates for strain-promoted copper-free azide-alkyne click chemistry reactions. DBCO compounds react with azide functionalized compounds or biomolecules without the need for a Cu(I) catalyst to result in a stable triazole linkage.
