DBCO-PEG2-Val-Cit-PAB-MMAE 

DBCO-PEG2-Val-Cit-PAB-MMAE is an ADC linker featuring a DBCO group, a Val-Cit dipeptide, a PAB motif, and an MMAE warhead. The DBCO group is a click chemistry handle which readily reacts with azide groups, while the Val-Cit is a protease-cleavable dipeptide which releases the MMAE warhead into cells via an elimination mechanism.

ADCs are comprised of an antibody to which is attached an ADC cytotoxin through an ADC linker.
