Fluorescein-DBCO 是一种不可降解 (non-cleavable) 的 ADC linker，可用于合成抗体偶联活性分子 (ADC)。Fluorescein-DBCO 是一种点击化学试剂。它含有 DBCO 基团，可以和含有 Azide 基团的分子发生环张力 (strain) 促进的炔-叠氮环加成反应 (SPAAC)。 Fluorescein-DBCO is a fluorescein dye derivative containing a DBCO group, which can react with azide-bearing compounds or biomolecules to form a stable triazole linkage without copper catalyst. This reagent can be an alternative for copper intolerant situations. Fluorescein-DBCO is a non-cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADCs)[1]. Fluorescein-DBCO is a click chemistry reagent, it contains a DBCO group that can undergo strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing Azide groups.
