DBCO-Sulfo-Link-biotin is a cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADCs)[1]. DBCO-Sulfo-Link-biotin is a click chemistry reagent, it contains a DBCO group that can undergo strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing Azide groups.
ADCs are comprised of an antibody to which is attached an ADC cytotoxin through an ADC linker.
