DBCO-PEG-Alkyne，凯新生物DBCO (dibenzocyclooctene) is a cycloalkyne, which can react with azide through 1,3-dipolar cycloaddition promoted by strain in aqueous solution, which is a biorthogonal reaction, also known as copper free click reaction. 该反应具有选择性和生物相容性，使得互补试剂可以与功能丰富的生物系统形成共价键。Copper free click reaction is a powerful tool for biocoupling without catalyst. DBCO reagent has fast kinetics and stability in water buffer, and can be used to label azide modified biomolecules with high specificity and reactivity.

Alkyne PEG is a kind of PEG linker, which contains three bonds that react with azide groups under mild conditions. 炔烃PEG应用于点击化学生物偶联、生物标记、化学生物学和抗体偶联物（ADC）.There are several different alkyne containing functional groups, such as propargyl, DBCO (dibenzocycloctyl) and BCN (bicyclic [6.1.0] nonyl). PEG arms increase the hydrophilicity of these connectors.
