DBCO-NHS ester 3

• Description:

  DBCO-NHS ester 3 (Compound 12) is a cleavable linker that is used for making antibody-drug conjugate (ADC) . DBCO-NHS ester 3 is a derivative of Dibenzylcyclooctyne (DBCO) obtained by activation of N-hydroxysuccinimide by the carboxylic acid moiety of both methyl-oxanorbornadiene (MeOND) and dibenzoazacyclooctyne (DIBAC) [1][2]. DBCO-NHS ester 3 is a click chemistry reagent, it contains a DBCO group that can undergo strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing Azide groups.
