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.
